EB-JWST-20 Intelligent Temperature and Humidity Transmitter
- Description
A temperature and humidity transmitter are low cost-sensitive electronic devices that detects, measures and reports both dampness and air temperature. The proportion of moisture noticeable all around to the highest amount of moisture at a specific air temperature.
It is one of the most important devices that has been widely in consumer, industrial, biomedical, and environmental etc. applications for measuring and monitoring temperature and humidity to a specific location especially in a data center or a sever room.
In most industries, temperature and humidity measurement is important because it played a role for a safety of all crucial equipment that may affect the whole operation.
Temperature and humidity sensor work by measuring the capacitance or resistance of air samples. Most of these transmitters 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.
