Light Sensor for Handy Cricket

Part Listing

The Cricket's sensor inputs can be used with resistive sensors, like the light-sensitive photocell. This makes a wonderful light sensor.

  • Photocell. The standard cadmium-sulfide (CdS) photocell works great with the Cricket. Ideally, you want one with a fairly high dark resistance (e.g., 500 Kohms) and a small light resistance (1K ohms or less).

  • One 3-position "DF3" plug for Cricket sensor port.

  • Two wires with pre-crimped "DF3" connector.

  • Three pieces 3/32" heat shrink.

Assembly Diagram

Notes: (1) The wires are inserted into the outer two of three positions of the connector header. (2) When soldering the wires to the photocell leads, be careful not to heat the leads for too long, or the photocell may get damaged.
