Temperature and Humidity Sensor Probe Cable SHT20 SHT30 SHT40 SHTC3 Anti-Condensation I2C Digital Sensor OEM Length 1M
1, A new generation of new Swiss Sensirion temperature and humidity chips.
2, 2C interface, digital signal output resolution up to 14 bits.
3, Fully calibrated, internal self-calibration.
4, Low power consumption, high reliability and excellent long-term stability.
5, The temperature and humidity are closely combined to facilitate dew testing.
6, It is sealed with waterproof glue to ensure that the circuit is not short-circuited in a humid environment.
7, It is suitable for temperature and humidity detection of cold chain, electricity, refrigerator, etc. The length of the cable can be customized.
Air relative humidity is a function of temperature, air temperature has a great influence on relative humidity, and various compounds such as acids, bases, salts, etc.
The physical properties have a significant impact, the following matters should be paid attention to when using:
1. The temperature and humidity sensor should be installed in a place where the temperature is relatively stable and can best represent the measured ambient temperature and humidity;
2. Avoid installing in places with drastic temperature changes;
3. Avoid installing in places with strong air flow;
4. Avoid installing in the dead corner where the air does not flow;
5. Avoid using it in a salt spray environment;
6. Avoid using in corrosive gas environment;
7. Sensors exposed to extreme working conditions or chemical vapors can be restored to their calibrated state by the following treatments;
Drying: keep more than 10 hours at 80¡É and < 5%RH humidity;
Rehydration: 12 hours at 20-30°C and >75%RH humidity conditions;
8. The internal temperature and humidity sensors and circuit parts of the module have been protected by silicone rubber, and are protected by a waterproof and breathable shell, which can effectively improve their performance in
Service life in high humidity environment. However, it is still necessary to pay attention to avoid the sensor being immersed in water, or using it under high humidity and condensation conditions for a long time;
