DM Devices offer a number of different inputs including:
- Digital Inputs
- Analogue (0-30V) inputs
- 4-20mA Inputs
Check each individual product's datasheet for the full specification, but inputs are generalised here:
|Digital Input||Dart2 (Ignition + 2)|
G100 (Ignition + 4)
G120 (Ignition + 6)
G62 Cellular (Ignition + 2)
G62 LoRaWAN (Ignition + 2)
|Digital Inputs with Pulse Count||SensorData Sigfox (2)|
SensorData LoRaWAN (3)
SensorNode LoRaWAN (2)
|Analogue Inputs (0-30V)||G120 (2)|
G62 LoRaWAN (1)
SensorData LoRaWAN (1)
SensorData Sigfox (2)
A brief description of each input:
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
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.
Common sensor output. Sensor will output 4mA when at the minimum of its range, and 20mA when at the maximum.
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.
Inter-IC communication. Low level communication interface which is used on many different sensor types.
Commonly used in the Ag-Tech space for soil moisture probes etc.
Generally used for I-Button Tags and readers.

|Temperature + Humidity||DM I2C Temp/Humidity Sensor||All DM Devices with I2C input|
|Ultrasonic Range||Maxbotix MB7040||Falcon|
|Infra Red||MLX90614||SensorNode, SensorData|
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.
I2C sensors are a common sensor type. 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.
Please contact DM so that the sensor can be integrated into device firmware.
Similarly if a particular BT sensor is desired, contact DM for integration information.
