DHT20 digital temperature and humidity sensor IIC signal output replaces DHT11 humidity sensing module
DHT20 is a new upgrade of DHT11, equipped with a dedicated ASIC sensor chip, a high-performance semiconductor silicon-based capacitive humidity sensor, and a standard integrated temperature sensor. It utilizes the standard I2C data output format. The performance and reliability of the upgraded sensor has been greatly improved and exceeds that of the previous generation.
This new product has been improved to make it more stable in high temperature and high humidity environments. At the same time, product accuracy, response time and measurement range have also been significantly improved. Each sensor is rigorously calibrated and tested before leaving the factory to ensure that it meets the needs of customers in large-scale applications.

Application
Indoor environment monitoring
Temperature and humidity sensor modules can be used for indoor environment monitoring in places such as offices, schools and hospitals. By measuring temperature and humidity in real time, the sensor module can provide accurate indoor environment data to help managers rationalize air conditioning and ventilation systems to provide a comfortable working and learning environment. In addition, the sensor module can also monitor indoor air quality and provide timely alerts and recommendations to improve the indoor environment.
Agricultural field
Temperature and humidity sensor modules are also widely used in the agricultural field. For example, in greenhouse cultivation, the sensor module can measure temperature and moisture to help farmers control the climate conditions in the greenhouse and provide a suitable growing environment. In addition, the sensor module can also monitor soil humidity to help farmers rationalize irrigation and improve crop yield and quality.
Warehouse logistics
Temperature and humidity sensor modules also have important applications in the field of warehouse logistics. For instance, in food and pharmaceutical warehousing, sensor modules can monitor real-time temperature and humidity in the warehouse to ensure product quality and safety. Sensor modules can also be integrated with logistics systems to provide accurately environmental data to help managers take timely measures to prevent product moisture, deterioration or damage.
