TH-341GB

Ethernet thermometer & hygrometer with GSM module and battery

TH-341GB is an extended version of our popular device TH-332A with integrated 2G GSM/GPRS module, 2200 mAh li-ion battery and one SPDT relay output. Besides the standard capabilities of all hygrometers, this device can detect internet and ethernet up/down events and also mains power failure. Each of these events can trigger SMS messages, email messages, Android push notifications, SNMP traps, Zabbix messages or activate the relay output. According to the current conditions, the device will automatically select the ethernet or the GSM module when sending that messages. The onboard battery allows normal device operation within 7 - 8 hours if no other power is available, and will be automatically recharged when the primary power is back on.
