RFQ
1. this sensor can measure soil temperature and humidity?
A: The definition of soil moisture is to take one kilogram of soil samples, thorough drying, reduced weight (weight of water) and 1 kg of the ratio becomes 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 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 be damaged, when faced with larger soil moisture, soil air humidity will long be 100%, measured on meaningless.
2. this sensor is soaked in water or condensation or buried in the earth whether damage?
A: We all were encapsulated sensor potting process, even with long-term immersion in water power will not be damaged, putting to dry the humidity is still normal acquisition.
3. sensor measurements after potting whether there will be an error?
A: Some manufacturers of packaged non-professional probe will have the following questions:
(1) Potting moisture absorption, especially in high humidity situations, once the increase of humidity does not drop down, because the potting lived in the reservoir water.
(2) After soldering, without making a resurgence treatment (many manufacturers even heard of the word), temperature and humidity cause large error.
(3) with temperature encapsulants, potting layer cracks caused by oxidation time, after dew drop caused by electrophoresis in the surface of the circuit board to form a fault.
4. Water proof ?
yes, perfect in water proof. don't worry
