What is Temperature and humidity sensor?
Temperature and Humidity Sensor is a low cost sensitive electronic meter that detects, measures and reports humidity and air temperature. The ratio of perceived ambient moisture to the highest moisture at a given air temperature.
It is one of the most important devices used in a wide range of consumer, industrial, biomedical and environmental fields to measure and monitor temperature and humidity in a specific location, especially in a data center or server room.
In most industries, the measurement of temperature and humidity is important because it plays an important role in the safety of all critical equipment and may affect the entire operation.
How Does It Work?
Agreeing to some expert, Temperature and humidity sensor work by measuring the capacitance or resistance of air samples. Most of these sensors utilize capacitive measurement to determine the amount of dampness in the air. This sort of measurement relies on two electrical conductors with a non-conductive polymer film laying between them to form an electrical field between them.
Moisture from the air collects on the film and causes changes within the voltage levels between the two plates. This alter is then converted into a computerize measurement of the air’s relative humidity after taking the air temperature into account.
(1)IP67 high-density material shell, built-in waterproof strip, moisture-proof and dust-proof. It can be used in harsh environments such as high temperature and humidity, dust, rain and snow. -40℃-80℃ can be customized.
(2)Support RS485 / 4-20mA / 0-5V / 0-10V / NB-IOT / Lora / 4G and other signal output to meet the environmental requirements. Wireless transmission, no wiring, low power consumption, stable performance.
(3)The temperature and humidity sensor products use high-sensitivity temperature-sensing elements, the sensor has high measurement accuracy and strong anti-interference ability.
The temperature and humidity sensor can be used to detect the temperature and humidity of industrial plants, traffic tunnels, energy, power and other harsh environment, as well as fruit trees, gardens, agricultural pastures, agricultural greenhouses, flower breeding and other machine rooms and laboratories.
