Temperature and humidity sensor SHT10 probe protective shell protective cover 20 flue-cured tobacco shed high humidity

Condition:New
Type:Logic ICs

Probe total length 59mm

1, imported sensors.2, all with a 10k pull-up resistor and filter capacitor 0.1uf3, all do double water treatment.4, before the factory on 100% electric aging test.

1, this sensor can measure soil temperature and humidity?
answer:Definition of soil moisture is to take one kilogram of soil samples, thorough drying, reduced weight (weight of water) and 1 kg of ratio is called soil moisture.
Relative humidity is defined as the percentage of saturated humidity absolute humidity and current temperature current temperature.
Fully air humidity with soil moisture is not a concept, nor is it an order of magnitude, while 10% soil moisture soil humidity of the air is already 100% up.

This sensor chip is sht10 or sht20, this chip is produced by the Swiss company Sensirion air temperature and humidity sensor for measuring the relative humidity of the air. This sensor through a special treatment,Long buried in the soil is not damaged, even if charged again boil the water will not damage (the Company exclusive commitments),When faced with larger soil moisture, soil air humidity will be 100% of long-term measurement would be meaningless.

2, this sensor is soaked in water or condensation or buried in the earth whether damage?

A: We have encapsulated sensorWholeWe conducted a potting process, even with long-term immersion in water power will not be damaged, putting to dry the humidity is still normal acquisition.

3. What is a double waterproof?

A: We sheath copper particle sintering or PE material, characterized by waterproof, breathable,Water molecules can enter the sheath, water droplets due to surface tension can not access sheath. In the case of high humidity, when the ambient temperature decreases the water molecules inside the sheath will form condensation water. If water droplets adhered to the circuit board, the board may make the electrophoresis and damage, so the company has been pouring on the board, and the use of special potting material, without any interference of the measurement.
