Figure 1: Pin assignment

 

 

2.1,Single bus connection

The microprocessor can be directly connected to the sensor. In single-bus communication mode, the SDA is connected to the I/O port of the processor after being pulled up.
Special instructions for a single bus:


1. In typical application circuit, it is recommended to use 10K pull-up resistance when the connection length is shorter than 30 meters, and then according to the length of the use distance
Short, adjust the size of pull-up resistance.
2. The read interval must be longer than 1S. If the time interval is too short, the temperature and humidity measurement may be inaccurate.

Application information

1. Working conditions
The recommended temperature range is -10 ° C to 60 ° C and the humidity range is 20-95%RH to ensure the normal and stable operation of the sensor. Exceeding the recommended range may cause temporary drift of measurement results.
2. Storage conditions and recovery
The humidity sensor is an environment-sensitive electronic component and requires careful protection. Long-term exposure to high concentrations of chemical vapors will cause the sensor's measurements to drift. Therefore, it is recommended that the sensor be stored in the original package and meet the storage conditions: Temperature range 10 ° C to 50 ° C; Humidity range: 20-60%RH. Sensors should be kept away from high concentrations of chemical solubilizers during production and transportation. Avoid using volatile glues, adhesive tapes, self-adhesive stickers, or volatile packaging materials such as foam bags and styrofoam.
3. Influence of temperature
Relative humidity depends a lot on temperature. The product has been calibrated and compensated for the temperature before leaving the factory. When measuring humidity, the sensor should be ensured to work at the same temperature as far as possible. When installed on the product, it should be kept away from the heat source as far as possible. Otherwise, the relative humidity of the gas cannot be accurately measured.
The sensor adopts passive communication mode, and is in sleep mode when there is no signal received, which is not only to save power but also to better control heat. Therefore, when in use, the wake up frequency should not be too high, otherwise it will be due to automatic heating effect. The recommended sampling period is 2 seconds.
