New RS485 module for Domoticz that read temperature and humidity, 4 inputs, 2 outputs, 3 LEDs
Posted: Wednesday 19 August 2020 23:55
DomBusTH is an electronic board that can be mounted in a blank module/cover with a 3mm dia hole in the centre, to measure temperature and humidity. The hole is needed to exchange air from room to the humidity sensor.
It's factory calibrated to get +/-0.3°C and +/-2%RH.
It also have 4 inputs, 2 open-collector outputs and 3 LEDs: each I/O/S is fully configurable from the Domoticz switch panel (through the device description).
DomBusTH can be connected to Domoticz through RS485 serial bus, 115200bps, as like as other DomBus devices (e.g. DomBus1, a module with 3/4 relay outputs, 6 inputs, 1 AC input). Using a shielded 4 wire cable, it's possible to connect all RS485 devices and supply them with 12V power supply (with backup battery, so the domotic system works even in case of power outage).

Example: DomBusTH installed beside bed switches, in the bedroom
The following diagram shows how it's possible to use DomBusTH in a bedroom to:
measure the room temperature and humidity;
control, by a pushbutton switch, the alarm system and white led:
alarm off, short pulse => enable night alarm and turn red Led ON for 2 seconds;
alarm on, short pulse => toggle white Led ON/OFF (can be used during the night to go bathroom without wake-up the partner);
alarm on, long pulse => disable alarm and turn green Led ON for 2 seconds;
control, by a double-pushbutton UP/DOWN, the roller shutters: two external relays are needed to drive the roller shutter motor UP/DOWN.
buzzer alert in case of intrusion detection (alarm) and in case that someone ring the door bell.
