6.2.4. Sensor connection
Up to 4 1-Wire sensors can be connected to
TCG120
controller. The device supports TSTxxx
(temperature) and TSHxxx (humidity&temperature) sensors.
1-Wire is a registered trademark of Maxim Integrated Products, Inc. It is designed to connect
several sensors over a short wiring. It is not suitable for long distances or environments with EMC
interference. We recommend reading Maxim’s 1-Wire tips at http://www.maxim-ic.com/app-
notes/index.mvp/id/148.
The sensors have three wires – positive voltage (+VDD), ground (GND) and bidirectional data (Data).
The colors of wires for every sensor are specified in its user manual.
It is strongly recommended to use “daisy chained” (linear topology) for multiple sensors:
