Wireless temperature sensor programmed with Arduino IDE

tinyBrd is small development board, with ATtiny84 and NRF24L01+ connector. With software provided by us, You get easy to use board which can send data by radio to Raspberry Pi or Arduino UNO and run many days (our most recent tests show it will run at least 2-3 weeks in this scenario) on single CR2032 battery.

When in sleep mode whole board with NRF24L01 and DS18B20 takes as low as 5 µA!

Tools and materials

To build this example You will need:

Of course You will need tools like solder iron, wire cutter, etc.

To receive data we suggest use Raspberry Pi and our NRF-Hat – simple board to connect NRF24L01+ directly to RPi, without mess (no cables required).
