7. Crowtail- Temperature& Humidity Sensor
Description
The Crowtail- Temperature& Humidity Sensor is based on DH11 which is a complex sensor with a
calibrated digital signal out.It used to detect the temperature & humidity.
8. Crowtail- Light Sensor
Description
The Crowtail- Light Sensor module incorporates a light dependent resistor (LDR), is a commonly
used sensor in a wide variety of applications from DIY projects to industrial automation. Typically,
the resistance of the LDR or Photo resistor will decrease when the ambient light intensity
increases. This means that the output signal from this module will be HIGH in bright light, and
LOW in the dark.
9. Crowtail- Vibration Motor
Description
This is a mini vibration motor suitable as a non-audible indicator. When the input is HIGH, the
motor will vibrate just like your cell phone on silent mode.
