Keyes Temperature and Humidity Sensor

Detail about Keyes Temperature and Humidity Sensor

DHT11 digital temperature and humidity sensor is a composite sensor contains a calibrated digital signal output of the temperature and humidity. Application of a dedicated digital modules collection technology and the temperature and humidity sensing technology, to ensure that the product has high reliability and excellent long-term stability. The sensor includes a resistive sense of wet components and an NTC temperature measurement devices, and connected with a high-performance 8-bit Microcontroller.

Low cost, long-term stability, relative humidity and temperature measurement, excellent quality, fast response, strong anti- interference ability, long distance signal transmission, digital signal output, and precise calibration.
