I would like to introduce you to one of my interesting projects. It is a wireless thermometer that measures the indoor and outdoor temperature. The device consists of two parts. One is a transmitter that contains one digital temperature sensor and a transmitter module. A second receiver consisting of an LCD screen, the analog sensor and receiving module.
1. Two arduinos any version
2. DS18B20 digital temperature sensor
3. LM35 analog temperature sensor
4. LCD 16×2
5: RF 433MHz or 315 MHz module
