Low-temperature temperature and humidity sensor for refrigerator and freezer.
■Operation Mode This product is equipped with a mode to switch the "transmission state" to reduce battery consumption when not in use. Please switch to the "stop state" before storing the product during transportation or when it is not in use. - Switching from "stop state" to "transmission state" Bring a magnet close to the magnetic detection part to turn ON, and move it away to turn OFF, using the following method for switching: ON for 5 seconds (Teach-in transmission) → OFF for 1 second or more but less than 10 seconds → ON for 5 seconds (Teach-in transmission and output transmission) - Switching from "transmission state" to "stop state" ON for 10 seconds or more (Teach-in transmission and output transmission while ON, and re-send Teach-in transmission after 10 seconds) → OFF (Teach-in transmission) In the "transmission state," when turned ON, it sends a Teach-in transmission and immediately sends an output once. After that, it sends an output once every specified time interval.

basic information
■About the Humidity Sensor - The temperature and humidity sensor used in this product is highly sensitive, and when used in extreme environments, it may generate an irreparable offset, particularly in humidity measurements. - A representative environmental factor that can adversely affect the operation of the humidity sensor is VOC gases. When exposed to a high concentration of vapor for an extended period, the humidity measurement values will gradually increase. Once the sensor's measurement values have risen, they are often irreversible. - Additionally, if the measurement part is directly touched, or if ethanol or cleaning agents are sprayed on it, or if items containing ethanol or cleaning agents come into direct contact with the measurement part, it may also adversely affect the sensor.
