Sensor Module

The Sensor Module features up-to four universal inputs or outputs on a pluggable terminal block with 1-Wire bus master support. The terminals can be used as both analog and digital input/output. For example you can connect various external digital, analog or resistive sensors. Also, you can communicate with other devices on a 1-Wire bus.

The Sensor Module features two universal inputs on a pluggable terminal block. The terminals can be used as both analog and digital input/output. For example you can connect various external digital, analog or resistive sensors. Also, you can communicate with other devices on a 1-Wire bus.

The two terminals - A on the left, B on the right - are connected to the BigClown header signals P4/A4/DAC0 and P5/A5/DAC1.

The C pin is in default configuration connected also to the ground GND. It is possible to remove zero-ohm resistor R20 and solder it to the place R21. This way the C signal is directly connected to P7 and can be used as extra input.

The VCC middle pin is possible to control by software. You can enable 3 V on this pin.

Hi, where could I find any successful project using a sensor module for water or electricity metering (analog binary input)? Thanks!

Hello, could you please give any parameters (limits for length and number of devices) for 1-wire topology? What are your recommendations for 1-wire design (like https://www.maximintegrated.com/en/design/technical-documents/tutorials/1/148.html)?

You can connect up to 2 sensors, if you would like to use more, you can use wago terminal blocks where you at first bring all 3 signals to 3 terminals from the Sensor Module and here you branch it up and connect individual sensors.
