Introduction

Temperature and Humidity Sensor features a calibrated digital signal output with the temperature and humidity sensor capability. it’s integrated with a high-performance 8-bit microcontroller. Its technology ensures high reliability and excellent long-term stability. This sensor includes a resistive element and a sensor for wet NTC temperature measuring devices. it’s excellent quality, fast response, anti-interference ability, and high performance.

Each DHT11 sensor features extremely accurate calibration of the humidity calibration chamber. The calibration coefficients stored within the OTP program memory, internal sensors detect signals within the process, we should always call these calibration coefficients. The single-wire serial interface system is integrated to become quick and straightforward. Small size, low power, signal transmission distance up to twenty meters, enabling a spread of applications and even the foremost demanding ones. the merchandise may be a 4-pin single row pin package. Convenient connections, special packages are often provided consistent with the user’s needs.
