Light Sensor for the Fire Fighter
We opted for the sensor from Mr
Sensor's homepage http://www.extremenxt.com/lego.htm.
- U1: LM 324
- R1: 1k
- R2: 47R
- C1: 16uF (Elco)
- D1-D6: 1N4148
- D7: Zener 5,1V
CdS2 Cadmium Photoresistor
- That's how we
arranged the differential light sensor into
Lego-bricks. The connector sorts at the back and
may easily be fixed at the RCX-sensor-entry.
- The sensor uses
power-supply from the RCX as being an active
sensor. The sensor input should therefore be set
to Light-Type. The mode should be set to
percent-mode. The returned values signify: 0 -
the light is entirely to the left; 100- the light
is on the right side.
