Description
The Controller GSM v4.2 is a small device with many possibilities. It can send sensor readings or execute on/off commands via SMS, connection, MQTT (via GPRS data transmission to server or application). The device also has the function of automating actions and sending notifications as a result of events or reaching a value.
A distinctive feature of the new GSM Controller is the configuration via the website. No additional cables, driver installation or special software are needed. The customer simply inserts the SIM card, turns on the device, logs into his account and, by entering his device identification number for the first time, adds it to his list of devices. Further settings are made through the configuration page on the mqtt.ats.pl server. The website uses the MQTT protocol to communicate with the device using GPRS data transmission. In the event that the SIM card does not use the default Internet access settings, we inform you in the installation procedure how to change the device settings via SMS.
Modes of operation:
Control by connection from an authorized number (in effect, it will turn on the relay and, for example, open the gate).
Control and receive information via SMS.
Controlling and receiving data by the server using the mqtt protocol.
Local automation using the conditions set on the device, which may result in e.g. switching on the output depending on the sensor reading.
NOTE: The GSM controller can work in all these modes simultaneously
Equipment:
2 analog inputs: for the 0-5V and 0-33V range, for measuring voltage, direct current (additional sensors needed), temperature sensors, photoresistors – dusk sensor, pressure sensor and many others

Digital input in I2C standard – for many different sensors or expansion of outputs
Serial bus (UART 3.3V)
2 logic inputs – as a status monitor (open/close doors, PIR sensors, etc.), as a manual switch button
1 relay (NO, C, NC)
