Ignition detection solution

Introduction

Ignition detection is a useful feature that we can implement into our connectivity solutions with some additional electrical components. In this article, we will show you two options on how to run the device depending on the state of Ignition:

• 1st option - the device turns on with the ignition and turns off when the ignition goes off.
• 2nd option - the device turns on with the ignition and stays on for some time, even if the ignition is turned off.

Schematics

The first schematic diagram provided gives you the ability to turn the device on and off depending on ignition state.

To build this schematic, you would need two electrical components:

• Diode

1N4001 diode or similar could be used. It is used to protect the control circuit from the sudden voltage spike. If the relay that you are using has a flyback diode built in, this diode is not needed. NOTE: if you are using this schematic without the diode, you risk damaging the device.

• Electromagnetic Relay

Relay choice depends on vehicle's electrical system voltage. If this setup is installed into a Vehicle with 12 V system, then a relay similar CM1-12V could be used. Otherwise, if the electrical system is 24 V, a relay similar to the CB1-P-24V could be used.
