About 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 terminals are connected to the HARDWARIO TOWER header signals. A - P4/A4/DAC0, B - P5/A5/DAC1 and C - P7/A6.


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