Digital Temperature and Humidity Sensor DHT11 Temperature and Humidity Sensor Module For Arduino NodeMCU RaspBerry PI

• 100% New and High Quality DHT11 Temperature and Humidity Sensor Module
• High Precision Relative Humidity and Temperature Measurement
• All Calibration, Digital Output
• Excellent Long-term Stability
• No Extra Parts Required
• Extra Long Signal Transmission Distance
• Ultra Low Energy Consumption

The DHT11 digital temperature and humidity sensor is a temperature and humidity composite sensor with a calibrated digital signal output. It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability. The sensor consists of a resistive wet sensor and an NTC temperature sensor connected to a high performance 8-bit microcontroller. Therefore, the product has the advantages of excellent quality, ultra-fast response, strong anti-interference ability and high cost performance for Arduino NodeMCU RaspBerry PI.

Each DHT11 sensor is calibrated in an extremely accurate humidity calibration chamber. The calibration coefficients are stored in the OTP memory as a program, and these calibration coefficients are called internally during the processing of the detection signal. The single-wire serial interface makes system integration easy and fast. Ultra-small size, extremely low power consumption, and signal transmission distances of up to 20 meters make it the best choice for even the most demanding applications. The product is available in a 4-pin single-row lead package.
