IR Obstacle Sensor module

Detects things like heat, distance, and movement by sensing infrared light

IR Infrared Obstacle Avoidance Sensor Module has a pair of infrared transmitting and receiving tubes. When the transmitted light waves are reflected back, the reflected IR waves will be received by the receiver tube. The onboard comparator circuitry does the processing and the green indicator LED comes to life.

The module features a 3 wire interface with Vcc, GND and an OUTPUT pin on its tail. It works fine with 3v3 to 5V levels. Upon hindrance/reflectance, the output pin gives out a digital signal (a low-level signal). The onboard preset helps to fine tune the range of operation, effective distance range is 2cm to 80cm.
Features:
Onboard detection indication
Effective distance range of 2cm to 80cm
A preset k**b to fine-tune distance range
There is an obstacle, the green indicator light on the circuit board

Type-C USB 3A Polymer Ternary Li-ion Lithium Quick Fast Charging Board IP2312 CC/CV Mode 5V To 4.2V

Charging Board, Type C Input Polymer Ternary Lithium Battery Fast Charging Module 3A for Lithium Battery
This Type-C USB Input High Current 3A Polymer Ternary Lithium Battery Quick Fast Charging Board, equipped with the IP 2312 main control chip, is designed for efficient and controlled lithium battery charging. It offers flexibility in charging currents and cut-off voltages, making it suitable for a variety of applications where fast and reliable battery charging is essential.

FEATURES:
The IP2312 uses a full CC/CV charging mode.
When the battery voltage is lower than 3V, it enters the trickle charge mode and charges the battery with a charge current of 100mA.
When the battery voltage is greater than 3V, enter the constant current charging mode to charge the battery with the set constant current charging current.
When the battery voltage is close to 4.2V and the charging current is less than 300mA, it enters the constant voltage charging mode. After entering the constant voltage mode, the charging is stopped after every 4 minutes, and the battery voltage is detected to be higher than 4.15V: if it is higher than 4.15V, the charging is stopped; otherwise, the charging is continued, and then the detection is performed after 4 minutes.
When the battery is fully charged, if it detects that the battery voltage is lower than 4.1V, it will turn on to charge the battery.
SPECIFICATIONS:
Main Control Chip: IP2312
Charging Mode: Full CC/CV charging mode
Input Voltage Range: 4.5V to 5.5V
Default Charging Current: 3A
Input Connector: Type-C USB
Charge Cut-off Voltage Options: 4.2V or 4.35V
Indicator Lights:
Work Indicator: Red
Full Charge Indicator: Blue
Dimension: 34.5mm x 15mm
