Grove Zero Touchpad

• Grove Zero Touchpad
• Features an input module to turn conductive objects
• Measures the ambient temperature in Celsius
• Composed of 4 touchpads labeled
• Turn on when the touchpad is connected to GND

The Grove Zero Touchpad measures the ambient temperature, in Celsius degree (℃) and relative environmental humidity levels (%). The module is composed of 4 touchpads labeled from 1-4. The metal contacts between the touchpad 1 and 2, 3, and 4 are GND (labeled as Earth onboard) that we can see in most of the circuits.

Use your fingertip to touch both a touchpad and the GND pad beside it, or connect them up with an alligator clip or 4 mm banana plug, then the corresponding switch is turned on.
