ESP32-CAM is a low-cost ESP32-based development board with onboard camera
Pipe Size: 1/2 inch Male (outer size)
It basically allows shifting levels between a TTL signal (0 - 5 V) and a RS232 signal (15 V - -15 V)
The entire sensor array has an IR filter over it that minimizes the effect of IR light on the readings

Optical (Infrared) Motor Encoder driver 30A ESP32-CAM is a low-cost ESP32-basedIntroduction: Optical (Infrared) Motor Encoder is a speed sensor. it is a type of tachometer that is used to measure the speed of a rotating object like a motor. It have an implemented contactless digital tachometer. There are many types of Speed Sensor like Hall effect based sensors, Magnetoresistive Speed Sensor, etc. Optical (Infrared) Motor Encoder inexpensive Infrared based Speed Sensor. Speed sensors serves the same purpose: help us determining
