A2D Analogue to Digital Adapter for OpenSprinkler

The A2D adapter allows two analog sensors to be connected. The switching point can be set precisely using a potentiometer per sensor input.

The range must be between 0-5V. Ground and power supply +5V DC are provided.

Digital sensors, such as rain sensors, can also be used. To do this, connect the rain sensor to the sensor and +5V. Set potentiometer to middle position.

Compatible with OpenSprinkler 3/3.2 AC+DC and OSPi from version 1.5. For older OpenSprinkler/OSPi only one sensor is available and +5V must be manually connected to a wire.

NOTE: The latest version of the adapter has a 7-pin connector strip as a connection element to the OpenSprinkler. With a few adapters, every other PIN was forgotten to be removed.
In order to be able to connect the adapter to the OpenSprinkler or OSPi, every second PIN must be removed. You can remove these, for example, with needle-nose pliers by bending them up and down and turning them several times. 3 pieces need to be removed: 2 + 4 + 6
