AHT20 AHT21 Digital Temperature and Humidity Sensor Measurement Module High Precision Sensor I2C Communication

introduce:

AHT21 is a new generation of intelligent temperature and humidity sensor based on semiconductor technology. The size is very small, the size is only 3*3mm, and the height is only 0.8mm. The compact size and its wide voltage adaptation range (2.2v to 5.5v) can be widely used. Applied to a variety of different equipment, the excellent performance endows it with good accuracy in a wide temperature range (-40℃~120℃). AHT21 is a dual-row flat no-lead SMD package suitable for reflow soldering, and outputs a calibrated digital signal in standard I2C format. The sensor is equipped with a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensing element and a standard on-chip temperature sensing element, which have the advantages of high quality, fast response, strong anti-interference ability and high cost performance. , its performance has been greatly improved or even exceeded the reliability level of the previous generation sensor (AHT10), and has been improved to make its performance more stable in harsh environments. Temperature and humidity sensors are most common in various scenarios such as home appliances, medical care, industry, transportation, smart agriculture, smart agriculture, meteorology, infrastructure, smart homes, and smart properties. Comparing the specifications of AHT21 and AHT20, AHT21 can detect a wider temperature range, from -40℃ to +120℃. The AHT21 also has a smaller size, with the height compressed to 0.8mm.
