PWM Solar Charge Controler Board 40 Amp

• Features of IR Sensor 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.
   

• Built-in on-board USB-TTL serial converter based on CH340G, with Micro-USB socket
• Power in for DC 4~9V DC to pin VIN
• Pin headers 2.54mm (0.1") 15 pins x 2 rows
• Arduino-like hardware I/O and can program in Arduino IDE
• Event-driven API for network applications
• 10 GPIOs D0-D10, PWM functionality, IIC and SPI communication, 1-Wire and ADC A0, etc. all in one board
• Wifi networking (can be used as an access point and/or station, host a web server), connect to the internet to fetch or upload data
