ASAIR Launches DHT20 capacitive Temperature And Humidity Sensor with a Fully Calibrated Digital IIC Interface

PublishTime： 2022-03-26 Article Source：ASAIR

DHT11 is a capacitive temperature and humidity sensor product independently developed and produced by ASAIR in 2009. With its good performance and excellent cost performance, it has always been welcomed by the market, and its products are sold well both at home and abroad. When DHT11 was discontinued, the market was flooded with copycat workshops using inferior resistive humidity sensors to counterfeit "DHT11", causing many customers to suffer heavy losses. Aosong Electronics reminds customers to avoid damage to their interests. Customers are requested to carefully identify the "ASAIR^®" trademark of Aosong Electronics and purchase high-quality sensor products.

DHT11 Product Appearance

With the continuous upgrading of advanced MEMS technology in sensor applications, Aosong Electronics has launched a classic-capacitive temperature and humidity sensor module, DHT11, which will withdraw from the stage of history! Instead, Aosong Electronics has carefully crafted a brand-new upgraded intelligent temperature and humidity sensor module, DHT20! This is a calibration-free, low-power, high-precision, high-stability product, with a fully calibrated digital IIC interface, fast response, strong anti-interference ability, and higher cost performance.

DHT20 Product Appearance

Comprehensive performance upgrade, extraordinary performance

DHT20 was developed "standing on the shoulders of giants." Relying on the successful research and development experience of a generation of classic DHT11, DHT20 is equipped with a brand-new temperature and humidity sensor chip in the module. In the sensor manufacturing industry, the accumulation of experience in project development is crucial. Aosong Electronics has nearly 20 years of R&D experience and expertise. With the support of the advanced MEMS semiconductor sensor chip production line, DHT20 has been comprehensively improved, with sufficient production capacity and stable supply. The product has an extraordinary performance. The performance of the product has skyrocketed. While reducing power consumption and cost, the performance parameters of measurement accuracy, power supply voltage, measurement range, response time, stability and other aspects have been greatly improved, far beyond The reliability level of previous generation sensors.

Performance Parameter Comparison Chart

Wide Range of Applications

Each product of DHT20 has been rigorously calibrated and tested before leaving the factory and can maintain stable performance even in harsh environments. It can be widely used in HVAC, dehumidifier, testing and inspection equipment, consumer products, automobiles, automatic control and data Recorders, weather stations, home appliances, humidity control, medical and other related temperature and humidity detection and control fields. Real-time monitoring of temperature and humidity changes in environmental scenes to better create a comfortable environment and better guarantee the safe storage of items.
