1M I2C Output SHT20 SHT30 SHT40 SHTC3 Temperature Humidity Sensor Module Probe Cable Waterproof Digital Capacitance Sensors
Product introduction:
temperature and humidity sensors are compatible with the digital temperature and humidity chip of Sensirion company. The sensor outputs calibrated digital signal, standard I2C format, and accurate measurement;In order to meet the customer's use in non PCB welding environment, waterproof design and lead installation are adopted to facilitate the use of customers.
Functional features:
1, New generation of Swiss Sensirion temperature and humidity chip.
2, I2C interface, digital signal output resolution up to 14 bits.
3, Complete calibration, internal self calibration .
4, Low power consumption, high reliability and excellent long-term stability.
5, Close combination of temperature and humidity is convenient for open measurement.
6, The waterproof glue is used to seal the circuit to prevent short circuit in humid environment.
7, Suitable for cold chain, power, refrigerator isothermal humidity detection, line length can be customized.
Storage conditions and precautions:
The air relative humidity is a function of temperature, and the air temperature has a great influence on the relative humidity. Acids, alkalis, salts and other compounds have a great influence on the physical properties of water vapor. The following items 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 installation in places with drastic temperature changes;
3. Avoid installation in places with intense air flow;
4. Avoid installation in a dead corner where air does not flow;
5. Avoid using it in salt fog environment;
6. Avoid using in corrosive gas environment;
7. Sensors exposed to extreme working conditions or chemical vapor can be restored to the calibration state by the following treatment: Drying: at 80℃ and humidity < 5%RH for more than 10 hours;
Rehydration: keeping at 20-30℃ and humidity > 75%RH for 12 hours;
8. The temperature and humidity sensor and circuit inside the module have been treated with silicone rubber protection and protected by waterproof and breathable casing, which can effectively prolong its service life in high humidity environment. However, it is still necessary to pay attention to avoid sensor flooding or long-term use under high humidity and condensation conditions;
