1.Description:
 It is a HTMRS3 temperature and humidity sensor.
 HTMRS3 digital temperature and humidity sensor is a temperature and humidity composite sensor with calibrated digital signal output.
 It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that the product has extremely high reliability and excellent long-term stability.

2.Feature:
 1).The sensor uses a high-performance polymer humidity resistance as the sensing element,which is converted into a digital signal output through the acquisition and processing of a single-chip microcomputer.It has the characteristics of long-term stability and high reliability.

 2).It is not affected by interference from power supply noise and voltage fluctuation,and can be used stably.
 3).It has high accuracy,low power consumption,and super cost-effective.
 4).Each HTMRS3 sensor is calibrated in an extremely accurate humidity calibration room,which can be accurately calibrated.

 5).The single-wire serial interface makes system integration simple and fast,with extremely low power consumption,and long-distance communication,making it the best choice for various applications and even the most demanding applications.
