I’ve tried the DHT11 sensor modules at both Vcc 3.3V and 5.0V, and at both voltages the humidity values are bad. dfrobot has introduced a V2 DHT11 sensor module that changes the 10K pull-up to 4.7K.

The sensor has got its own proprietary 1-wire protocol to communicate with a host microcontroller. DHT11 sensor. The following timing diagram describes the protocol involved in the communication ...

The traditional cable data transmission is high cost and big interference. instead, the wireless data transmission has advantages like: low cost, better applicability and lower interference. So, a ...

Overview of DHT11 Sensor: The DHT11 sensor can measure relative humidity and temperature with the following specifications. Temperature Range: 0-50°C Temperature Accuracy: ±2 °C Humidity Range: 20-90% ...

Abstract: The traditional cable data transmission is high cost and big interference. instead, the wireless data transmission has advantages like: low cost, better applicability and lower interference.
