NEO-6M GPS Module

• When the module detects obstacles in front of the signal, the circuit board green indicator light level, while the OUT port continuous output low-level signals, the module detects a distance of 2 ~ 10cm, detection angle 35 °, the detection distance can be potential adjustment with adjustment potentiometer clockwise, the increase in detection distance; counterclockwise adjustment potentiometer, the detection distance decreased.
• the sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The black minimum detection range, white maximum; small area object distance is small, a large area from the large.
• The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO.
• The comparator using LM393, stable.
• 3-5V DC power supply module can be used. When the power is turned on, the red power LED is lit.
• With the screw holes of 3mm, easy to install.
• Board size: 3.1CM * 1.5CM.
• Each module in the delivery has threshold comparator voltage adjustable via potentiometer, special circumstances, please do not adjust the potentiometer.

Features :

1. Indicator light: a green one for the switch, a red one for power.
2. Built in a potentiometer for sensitivity control.
3. Onboard signal output indication, output effective signal is high, at the same time the indicator light up, the output signal can directly connect to microcontroller IO.
4. Can detect fire or wavelength in 760 ~ 1100 nm nano within the scope of the light source.
5. Detection angle about 60 degrees, the flame spectrum especially sensitive.
6. The flame of the most sensitive sensors flame, the regular light is also a response, generally used for fire alarm purposes.
