Type:Logic ICs
Condition:New
You can use the following sensor on a large number of
1, the original import sensor.
2, all with 10K on the pull resistor and 0.1uF filter capacitor
3, all do double waterproof treatment.
4, 100% on the electrical aging, inspection.
The air temperature and humidity sensor, the whole double water treatment, completely Ninglu damage. Note: even if the sensor is buried in the soil, it is also a test of the soil.atmosphereRelative humidity, not soil moisture.
1, this sensor can measure the soil temperature and humidity?
Answer:The definition of soil moisture is to take 1 kilograms of soil samples, and thoroughly dry, reducing the weight (water weight) and the ratio of 1 kg to become the soil moisture.
Air relative humidity is defined as the absolute humidity of the current temperature and the percentage of the saturated humidity of the current temperature.
10%100%.
sht10sht20Long term buried in the soil is not damaged, even if the charged water in the water will not be damaged (the company's exclusive commitment),When the soil is slightly larger in the face of humidity, the air humidity in the soil will be 100% for a long time.
2, the sensor in the water or dew or buried in the earth or damage?
Answer: We package the sensorwholeThe sealing treatment, even with a long soak power will not be damaged, in the water out, dry humidity is still normal acquisition.
The sensor measurement results of 3, after the pouring whether there will be errors?
A: some of the non professional manufacturers package will have the following questions:
(1) potting moisture absorption, especially high humidity and humidity occasions, once growth does not drop down, the reason is in the water storage for potting.
(2) after welding without dampening treatment (many manufacturers did not even heard the word), causing great error of temperature and humidity.
(3) sealant with temperature, long time oxidation caused by encapsulating layer crack, causing condensation drop after electrophoresis in the surface of the circuit board, the formation of fault.
The company's products to overcome the above problems, it is recommended to carefully identify when buying products. Ask each technical details and be responsible for your product,To put an end to certain businesses",We welcome you to our technology.
4, what is the double waterproof?
A: the store jacket is copper particles sintered or PE material, is characterized by waterproof breathable,Water molecules are able to enter the sheath, and the water droplets are unable to enter the sheath due to the surface tension.. In case of high humidity, when the ambient temperature decreases the water molecules inside of the sheath will condense into water. If the water droplets attached on the circuit board, the circuit board may make electrophoresis and damage, so the company was pouring on circuit board, and the use of special potting material, without any interference on the measurement value.
