Wireless Weather Station with Rain gauge


This desktop weatherstation is perfect for those  who want to know the temperature, rainfall and contrast of indoor and outdoor temperatures.

The weather channel information is not very local, having your own weatherstation give you precise local weather info. This home weather station has an external

sensor which collects the outside temperature and rainfall data and sends it wirelessly to the indoor display.

The rainfall gauge is a very useful feature which is only seen in expensive weatherstations, this product has that and comes with a very reasonable price tag. The external unit has a range of upto 100m allowing placement at a decent location for gauging the weather outside.

The rain gauge is easy to mount outside, using the screws included, is self-emptying and has more than 1 years battery life meaning you can set and forget.

It comes with a detailed instruction manual of operation.


1) Rainfall display range: 0 to 19,999mm

2) Outdoor temperature range: -40 ~ +65°C
3) Indoor temperature range: -9.9 ~ +60°C
4) Temperature accuracy: ±1.0°C

What is Arduino

Arduino is an open source computer hardware used for building digital devices and interactive objects that can sense and control objects in the physical world. The project's products are distributed as open-source hardware and software, which are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL) permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially in preassembled form, or as do-it-yourself (DIY) kits.

Arduinos are programmed using the Arduino IDE which can be downloaded from here :

Why is Arduino so famous?

Arduino's are simple to use and program. It is used by a wide variety of people some who have a programming background to other who range from artists and DIY enthusiasts.

Arduino comes with a lot of free libraries making it easy to connect to different hardware, like a LCD display or a smoke sensor or even controlling a robot.

We at hobbyist provide a lot of kits build around the Arduino ecosystem, all our kits comes with all the bits needed including the source code.

This makes it very easy for they buyer to build the kit and get it going, we provide awesome technical support if at all you get stuck using any of our kits.

Some of our tutorials include :

Mars Rover: A kits set to build a complete robot which can be controlled wirelessly from your mobile or laptop

Fingerprint scanner : door security kit


Having problems with memorising the password? Forgetting the combination code?
With the Fingerprint Sensor Kit you can protect your treasures or secrets using your biometric ID.
ie your fingerprint.

Fingerprint is your unique signature which you carry with you everywhere you go, so unique that you
can use it to open locks and use it as your password.

It is complicated to build a complete system to do your own fingerprint sensing and integrate it with a lock,
For this reason we bring a complete kitset with step by step instructions to get going a Biometric fingerprint kit
which can open a door lock.

Our Kit in action - Biometric Door Lock:

Fingerprint scanner, biometric system, biometric devices, attendance system, fingerprint reader, fingerprint technology, biometric card, fingerprint attendance system, fingerprint login,


1. Adding fingerprints to the reader

2. Assembling the fingerprint scanner kit parts and testing it works

3. Building the complete biometric kit with scanner and a OLED display

Wifi Datalogger and monitoring system


Industrial and commercial projects need constant monitoring of sensors and collection of data in a format which is readily accesible and can be visualized with ease. For solving this problem we have developed a Datalogger and monitoring system which works over Wifi.

  The beauty of this system is its entirely self sufficient, Does not need an existing wireless network. It simply creates its own Wifi access point and
the you can connect to it simply with a PC, android or Iphone.

What does this mean:

This means the user is able to monitor the temperature sensors connected to the datalogger in these simple steps

1. Smart phone (iphone, android ) or your PC sees "DATALOGGER" wifi network, simply connect to it.

2. Download the logged data in the format of Excel readable CSV files

3. See live graphs by clicking following this URL.

This device can be used for monitoring temperature for soil, industrial monitoring systems, vineyards etc. We do provide support to add different type of sensors to cater for other datalogging uses.

What comes with the purchase:

  • Datalogger
  • 2 x Temperature sensors (water proof,  -25 - 125 DegC range)
  • 5v Power adapter


1. Can this Datalogger connect to other sensors other than the ones which comes with it ?
A. Yes, we already have support for K type thermocouples ( works upto 500 Deg C ) as well as others, just contact us and post your needs we can get it working for you.

2. Will this sensor work in places with no Wifi coverage?
A. Yes, Since this device creates its own Wifi network, it can work in areas where there is no wifi coverage.

3. How does the graph look like?
A. The graphs would have the same look and feel as this one ( NOTE: For the datalogger the data would be 2 Temperature series lines )

4. Can I see a sample of the Excel readable file which the datalogger creates? 
A. This sample CSV file was created by the logger. You can download it and view it in Excel. ( or openOffice ) 

3. Can I get you to add more temperature sensors of the same type to this logger ?
A. The standard package comes with 2 Temp sensors ( -25 - 125 DegC range),  for sure we can add more sensors to the Logger for a small cost.

4. Does this device need any assembling or is this a plug and play device ?
A. This is a plug and play device with no assembling required. You just have to power it and it should just work out of the box.

5. How do I view the graphs once the Datalogger is powered up ?
A. From your Mobile/PC connect to the Wifi network called 'DATALOGGER'. Once connected you can view the graphs by
    accessing this link

Wifi weatherstation kit with Live Graphs


The devices which connect to internet has been shrinking at very fast pace, Now its got to the size which fits on your fingers and can not only connect to the internet but as also do some sensing.

ESP8266 chipset has made waves since it got introduced, Due to its small size and capablities. This is the first generation of IOT technologies which is going to change the way we live.

We use this powerful tiny module to build a complete WeatherStation kit, which collects Temperature, Humidity and Barometer readings. Not only does it collect the data, It stores it in the cloud for you to watch the data in the form of live Graphs from any device be it your mobile, PC or tablet. Isnt that cool....

With the purchase of the kit we give you a unique key, which is used to provide access to the cloud storage to store it as well as download the data.

Click here to see the Live Demo graph

You can use this kit for many purposes:


                   Fig: Electronic Barometer + Temperature + Humidity sensing

Wireless Sensor and Data Logger


What can this box do?

This kit takes measurement of its two precision temperature sensors, and logs the data to a SD card. Both real time readings and stored data can be sent wirelessly to a PC.

How is it useful?

One of the two temperature sensors is located inside the box, and the other one outside on a 1.2 meter cable. By locating the two temperature sensors in two different areas (e.g. indoor and under floor). We can see the temperature variations of the two areas over time. One good use case is to measure how good your home insulation is. Having said that, this kit is designed with DIY in mind. Extra sensors can be added very easily, and soldering is minimum because of the use of the sensor shield. By adding a humidity sensor, light sensor, wind speed sensor etc, this box can be turned into a wireless weather station!

What is included in this kit?

This wireless sensor and data logger kit embodies a few very cool technologies: Real Time Clock, SD Card read/write, Bluetooth and one wire digital temperature sensor. Not only can it be easily turned into a general purpose wireless sensor logger, it also is a fantastic educational kit after all. This kit includes all the neccessary bits to construct a fully working wireless sensor logger, the package includes:

  • Arduino Mega 2560
  • Arduino Mega sensor and servo shield
  • USB cable
  • Real Time Clock module (onboard temperature sensor incl.)
  • SD card module
  • Kingston SD Card 1 GB
  • Bluetooth module
