IoT Motion Detector With NodeMCU and BLYNK -

If you are sure that you sensor generates and not 5V as output you can eliminate the level converter, connecting NodeMCU Pin D1 (GPIO 5) directly to HC-SR501 Output. We have also included a LED at pin D7 (GPIO13), for a local visualization. Step 4: Testing the sensor. First let's us do a simple test for testing and calibrating the sensor. Upload the below code at Arduino IDE: /* HC-SR501 ...

Arduino lesson – IR Obstacle Avoidance Sensor «

· Light reflected from the LED is detected by a IR receiver module. The receiver module incorporates an external, optical, 950nm IR filter and an internal, electronic, 38kHz band-pass filter that make the module receptive only to IR light pulsing at that frequency. The Infrared Obstacle Avoidance Sensor has Power, Ground, Signal, and Enable pins.

Nodemcu ESP8266 - Lab 14 IR Sensor With Blynk App ...

Using the <#define IR D7> statement, the pin D7 of the NodeMCU was defined as the IR pin where the output pin of the IR module would be connecte. After that variable “ir” is defined with the “bool” data type (since it will be used later in the code for reading the output of the IR module which can be either HIGH “1” or LOW “0”). Then in the function, the serial ...
