Input Descriptions

Digital Inputs:
Used to determine on/off status. Will be registered as 0 (off) or 1 (on).
Typical applications include panic buttons, door open closed, monitoring engine on/off, run hours when connected to a PTO
Analogue Inputs:
Can be connected to a variety of sensors e.g. Temp Sensor, ultrasonic sensor etc, that output a certain voltage based on the temp/distance etc. This can be thought of as a voltage input.
Can also be used to read 4-20mA signals when combined with a sense resistor.
4-20mA:
Common sensor output. Sensor will output 4mA when at the minimum of its range, and 20mA when at the maximum.


BLE:
Some Digital Matter Devices have a BLE 5 Module on board. This means that any sensor that uses Bluetooth could be integrated into the device FW so the sensor can be read.
I2C:
Inter-IC communication. Low level communication interface which is used on many different sensor types.
SDI-12:
Commonly used in the Ag-Tech space for soil moisture probes etc. 
1-wire:
Generally used for i-Button Tags and readers. But some 1-wire sensors (e.g. temp) exist

Integrating sensors across multiple devices requires firmware development per device - as such a single sensor integration is not rolled out across all devices with the same input immediately (or even at all if it is not required). 

If you want to use one of the above sensors with another device, contact us.


I need to use a sensor that isn't listed here, what are my options?

If an application requires a particular sensor that is not currently catered for, DM can integrate sensors. Typically a sensor which utilises one of the above inputs can be integrated with firmware development. 

Most common are I2C sensors. I2C is a low level communication interface, so simply connecting an I2C sensor to a product with an I2C input in general will not work - the firmware must be modified.
Note for these sensors, The sensor should be able to be powered by a 3.3V source. As this is what is available to power sensors on DM devices. If it requires greater than this it will need to be powered externally to the device.

Please contact DM so that the sensor can be integrated into device firmware. Similarly if a particular Bluetooth® sensor is desired, contact DM for integration information.
