1 Port Digital Input Device with Temperature/ Humidity (DIO-1HT)
Features
DIO-1HT (1 Port Digital Input Device with Temperature and Humidity) provides 1 digital input port and the measurement of temperature and humidity.
DIO-1HT device can transmit the digital values (Binary 0 or 1) and the measured values (temperature and humidity) using (1) MQTT/WiFi, (2) WiFi and (3) LoRa techniques. Method (1) sends MQTT messages to the remote MQTT broker directly. Methods (2) requires MQTT server and method (3) requires LoRa MQTT Gateway to relay the received messages to the MQTT Server. Messages processed in the MQTT Server can be displayed in the remote PC monitor via a private VPN link.

DIO-1HT with MQTT
Method (1) MQTT/WiFi is the simplest way to send messages to the MQTT broker in the Internet and be relayed by the MQTT broker and received by the APP in the smart phone.
DIO-1HT interfaced with Digital Input Modules: (1) Door/Window Magnet, (2) Emergency Button, (3) PIR, (4) CO Detector, (5) Smoke Detector, etc., will show the ON/OFF states of the inputs. DIO-1HT is also designed with Humidity and Temperature sensors.
The Digital Input which sends (publish) Topic 1 for the digital input state, Topic 2 for temperature value and Topic 3 for humidity value to the public EMQX broker via the Internet. The public EMQX broker re-sends the messages to the Smart phone, i.e., the Smart phone subscribes Topic 1, Topic 2 and Topic 3 to the public EMQX broker.
The Smart phone recieves the MQTT messages and uses the APP (MQTT Panel) to diplay tthe received digital input values and the temprature and humidity values as shown in the upper red box.
