Wireless Temperature Measurement

This one is a little different project related to temperature measurement. Apart from being wireless, it measures both indoor as well as outdoor temperature. It’s made in two parts. The first part consist of the temperature sensor and the transmitting module, while the other one has the receiving module, an analog sensor and the display. The parts used in this project are easily available at the local hobby shop. Hey comprises of two Arduino, an lm35 sesnor, a ds1820 digital temperature sensor, an lcd and a receiving and transmitting module For the project, you will require three sets of library. Two are for digital sensor and one for rf module. All of them are available on the project website. Overall an excellent project for beginners who has just started to learn Arduino. It will teach you about LCD interface, wireless interfacing and also sensor interfacing. To those who want to try the code along with complete schematic is available on the project website.

RF temperature value transmitter

Main benefit of using wireless temperature sensor is that you can put it anywhere without thinking of wires. But to make this set up you’ll need at least two microcontrollers, transmitter and receiver modules and separate power supply solutions. Richaarddd in his instructable explains how to build simple, cheap wireless temperature sensor using Picaxe microcontrollers and 433.9MHz RF modules. Temperature is sensed with 1-wire DS18B20 digital temperature sensor. Continue reading
