A2D analog to digital adapter for OpenSprinkler

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

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

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

Compatible with OpenSprinkler 3/3.2 AC+DC as well OSPi from version 1.5. For elderly OpenSprinkler/OSPi only one sensor is available and it must be manually connected to +5V with 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 it was forgotten to remove every 2nd PIN.
To the adapter on OpenSprinkler or OSPi to be able to connect, every second PIN must be removed. You can remove these by bending them up and down and turning them several times, for example with needle-nose pliers. 3 pieces must be removed: 2 + 4 + 6
