Wireless Humidity and Temperature Transmitter – Arduino
The project presented here is a Wireless Humidity and Temperature Transmitter that utilizes a DHT22 sensor to measure temperature and humidity levels. The data is then transmitted via an NRF24L01 RF transceiver module to a receiver board, which displays the readings on an OLED display.
Components
- DHT22 humidity/temperature sensor
- Arduino microcontroller (ATMEGA328)
- NRF24L01 RF transceiver module
Features
- Power supply: 5V DC
- Onboard temperature and humidity sensor (DHT22)
- Power LED onboard
- Onboard 3.3V regulator for NRF24L01 module
- Compact PCB design (dimensions: 34.13 x 16.03 mm)
- Header connector for power input
