Gravity: AHT20 Temperature and Humidity Sensor

The AHT20 is an outstanding temperature and humidity sensor. It offers high precision at a low cost, thanks to its improved MEMS semiconductor capacitive humidity sensor element. With a standard I2C interface and a wide 2V - 5V voltage supply, it's very versatile. Its simple peripheral circuit ensures stable performance even in harsh environments from - 40°C to + 85°C. This sensor can be used in various applications, such as measuring the environmental temperature and humidity of home electronics and in automobiles. It features digital output with an I2C interface, excellent long - term stability, fast response, strong anti - interference ability, and good adaptability. The Gravity interface makes wiring simple without soldering. It's suitable for HVAC, dehumidifiers, testing equipment, consumer appliances, automobiles, automatic control, data loggers, and weather control. Its module parameters include an operating voltage of DC2V - 5V, an I2C output signal, an I2C address of 0x38, and dimensions of 30mm×20.5mm (1.18×0.81 inches). The AHT20 chip has high - quality relative humidity and temperature parameters. For relative humidity, it has a resolution of 0.024 %RH, an accuracy error of ±2 %RH, etc. For temperature, it has a resolution of 0.01°C and an accuracy error of ±0.3°C. The package includes one Gravity AHT20 Temperature and Humidity Sensor and one Gravity - 4P I2C/UART Sensor Cable.

Using the Gravity AHT20 Temperature and Humidity Sensor is easy. First, connect it to your device using the provided Gravity - 4P I2C/UART Sensor Cable. The simple wiring means you don't need to solder anything. Once connected, it will start measuring the temperature and humidity right away. When using it, make sure the operating voltage is within the 2V - 5V range. Also, avoid exposing it to extreme conditions outside the - 40°C to + 85°C temperature range and 0 - 100 %RH humidity range. For maintenance, keep it clean and dry. If you notice any abnormal readings, check the connection and the power supply. This sensor is very stable in the long - term, but it's still a good idea to check it regularly for optimal performance.
