TP4056 Module Lithium Battery Charger with Protection Micro USB

The optical module sensor (reflective) with comparator LM393, which detects obstacles with high precision.
The ideal obstacle detection detector for the installation of smart robots.
TCRT5000 - reflective optical sensor that has a compact construction where the light emitter and receiver are placed in the same direction to detect the presence of a object using infrared reflection on the object.
The working wavelength is 950nm.
The transmitter is infrared LED and the phototransistor receiver.
By using LM393 comparator the module has a binary output (D0) that is at level 1 (object is detected).
The sensor allows the detection of an object at a distance of up to 12 mm.

- Angle detection of about 60 degrees,
- This light can be detected by an optical sensor,
- Can be captured by digital inputs and analog inputs of Arduino.

This module includes the BMP280 component that converts atmospheric pressure, temperature and humidity with high precision into a digital signal.
The equipment uses the two I2C and SPI interfaces. The very good measurements made by the BMP280 allows the module to be used as an altimeter.
Its 5-pin straight connector allows easy connection to other electronic boards. BMP280 Temperature Barometric Pressure Sensor Module/SPI features:
- Interfaces:
       -I2C (up to 3.4 MHz)
       -SPI (up to 10 MHz)
- Supply voltage: 1.8-5VDC
- Module operating range:
       - Temperature: -40ºC to + 85ºC
0-100%
