Tunnel – Remote management of up to 9 digital outputs and relays through Telnet and/or MQTT/S.

Senario details: You need to be able to change the status of 9 remote relays to enable / disable a number of devices connected to them. Such remote activation needs to be done through telnet and / or an MQTT / S platform. For telnet access, only TCP connections must be allowed from authorized IPs […]

Tunnel – Activate a relay by voice call and by dry contact inputs to open the parking gate.

Scenario details: You need to be able to operate a relay with a 5 second pulse to open a motorized garage door. Such activation needs to be done by voice call through a mobile phone It should only be possible to operate the relay from the authorized telephone numbers: +34666123456, +34666123457 and +346661234568 It must […]

Tunnel – Change by SMS of up to 9 digital outputs or 9 relays.

Scenario details: You need to be able to change the status of 9 remote relays to enable / disable a number of devices connected to them. Such remote activation needs to be done by SMS messaging It should only be possible to change the status of the relays from the authorized telephone numbers: +34666123456, + […]

Tunnel – Instant sending of telemetries via MQTT of up to 2 analog inputs 0-10V and 4-20mA.

Scenario details: 2 analog sensors need to be monitored, one of the 0-10V type and the other of the 4-20mA type The monitoring of the analog sensors will be carried out using MQTT, that is, the modem must send the data from both sensors to an MQTT broker In order to save bandwidth, there is […]

Tunnel – Instant sending of telemetry via MQTT of up to 8 digital inputs.

Scenario details: 8 dry contact sensors need to be monitored. In the state of the entries, it must be sent quickly to an MQTT platform (example Cervello) when a change occurs in one of them For the first four inputs, the modem must be configured to send via MQTT any state change that occurs in […]

Tunnel – Voice call alarm to change up to 2 analog inputs of 0-10V and 4-20mA.

Scenario details: 2 analog sensors need to be monitored, one 0-10V and the other 4-20mA If the 0-10V sensor registers a voltage greater than 8V or less than 2V, an alert voice call must be made to a series of telephone numbers If the 4-20mA sensor registers a current greater than 16mA or less than […]

Tunnel – Voice call alarm to change up to 8 digital inputs.

Scenario details: 8 dry contact sensors need to be monitored In the event of an activation in any of them, a voice call must be made to several phone numbers The phone numbers that will receive the SMS alerts are +34666123456, + 34666123457 and +346661234568 To avoid making a large number of voice calls (in […]

Tunnel – SMS alarms to change up to 2 analog inputs.

Scenario details: 2 analog sensors need to be monitored, one 0-10V and the other 4-20mA If the 0-10V sensor registers a voltage higher than 8V or lower than 2V, an alarm SMS message must be sent, indicating the type of alarm. You must also inform with another SMS in case the alarm is deactivated If […]

Tunnel – SMS alarms to change up to 8 digital inputs.

Scenario details: 8 dry contact sensors need to be monitored In the event of a state change in any of them, an SMS message must be sent to several phone numbers. Each dry contact must have a personalized message that identifies the sensor that caused the alarms, as well as whether the alarm was activated […]

Tunnel – Periodic monitoring by 4G/3G/2G of 0-10V sensor activating the power supply of the sensor through a relay output of the modem. Sending to web server using HTTP GET.

Scenario details: It is intended to monitor a 0-10V sensor with a 4G/3G/2G modem The modem and the sensor will be powered by solar panels, so energy consumption is important For this reason, the sensor to be read will be powered through the internal relay with the MTX-IOT-S modem associated with its GPIO8 output. That […]
