SWSN-HAThe wireless temperature and humidity transmitter (indoor temperature and humidity collector) is a high-precision, low-power wireless transmission type temperature and humidity detection instrument independently developed by our company. Powered by lithium batteries, there is no need for wiring or external power supply, which eliminates the trouble of laying cable trays for conventional instruments, saves manpower and construction costs, and is an ideal upgrade product for traditional temperature and humidity instruments. The SWSN-HA-NB adopts the NB-IOT standard, which is particularly suitable for indoor temperature and humidity data collection for heating users.
