1. Work and storage conditions that exceed the recommended operating range can lead to a temporary drift signal of up to 3% RH. When the normal operating bar is returned, the sensor slowly returns to the calibration state. To speed up the recovery process, see "Recovery" in Section 3. Long-term use under abnormal operating conditions accelerates the aging process of the product.Exposure to chemicals The sensor layer of the resistance moisture sensor is blocked by chemical vapor, and the diffusion of chemicals in the sensor layer can cause measurement to drift and decrease sensitivity. In a pure environment, contaminants are released slowly. The recovery process described below speeds up this process. High concentrations of chemical impurities can cause complete damage to the sensor layer of the sensor.3. Recovery processing Sensors placed under extreme operating conditions or chemical vapors can be restored to state at the time of calibration in the following steps. Humidity is 50-60°C, 10% RH for 2 hours (dry), and humidity holds 20-30°C and .70% RH for 5 hours or more.4. Temperature affects the relative humidity of the gas, which depends heavily on the temperature. Therefore, when measuring humidity, the humidity sensor must be as safe as possible to operate at the same temperature. When sharing a pressure cable plate with an electronic component that emits heat, the DHT11 must always be kept away from the electronic device and placed under a heat source while maintaining good chassis ventilation. To reduce thermal conductivity, dht11 and copper coating on other parts of the printed circuit board must be minimized and the distance between the two must be kept between them.5. Light is exposed for a long time to too much sunlight and intense UV rays and degrades performance.6. Wiring note DATA signal line quality is recommended to use high quality shielded wire, which affects communication distance and communication quality.
