TH-355

Ethernet thermometer & hygrometer with IO

TH-355 is an extended version of our popular device TH-332 with added 2 galvanically isolated digital inputs and one SPDT relay output. A out-of-range condition of any of the monitored parameter or change of the inputs can trigger email messages, android push notifications, SNMP traps, HTTP request to predefined host and/or can activate the output relay that can be used for additional signalling trough sirens, lamps or even to be connected as a sensor to your alarm or fire system. The inputs can be used to connect various external sensors, like magnetic door sensor, fire or smoke sensor, water leak sensor, etc. The output can be configured in 3 different working modes - follow mode, single impulse mode and square wave mode with selectable period and duty cycle. If needed, the device can be used even as a two-positional regulator, but should not be used for critical applications, as that's not its primary function.
