GPRS/4G/Wi-Fi Tempreture Transmitter
NT-L1T series temperature transmitter is designed for temperature humidity of logging, monitoring,alert and control. It comes with temperature probe, and transmit data by GPRS/4G or Wi-Fi. NT provide free cloud service, real-time data dashboard, graph, history records can be shown on web and APP. And alert by email or sms. With output, it supports temperature control by remote or local.
