DHT11
DHT11 is Humidity & Temperature Sensor manufactured by Unknown Manufacturer.
features a temperature & humidity sensor plex with a calibrated digital signal output. By using the exclusive digital-signal-acquisition technique and temperature & humidity sensing technology, it ensures high reliability and excellent long-term stability. This sensor includes a resistive-type humidity measurement ponent and an NTC temperature measurement ponent, and connects to a highperformance 8-bit microcontroller, offering excellent quality, fast response, anti-interference abilityand cost-effectiveness.

Each DHT11 sensor is strictly calibrated in the laboratory that is extremely accurate on humidity calibration. The calibration coefficients are stored as programmes in the OTP memory, which are used by the sensor’s internal signal detecting process. The single-wire serial interface makes system integration quick and easy. Its small size, low power consumption and up-to-20 meter signal transmission making it the best choice for various applications, including those most demanding ones. The ponent is 4-pin single row pin package. It is convenient to connect and special packagescan be provided accordingto users’ request.
