This is TCRT 5000 Dual Channel Line Tracking sensor module.

This IR reflective sensor Module used TCRT5000 IR Sensor to detect color and distance. This sensor module consists of an IR transmitter & an IR receiver. IR Transmitter continuously emits IR signal which is then reflected by an obstacle and is then detected by the IR receiver.

TCRT5000 Infrared Reflective Sensor Module is often used in line following robots, object sorting Robots because this module can sense if a surface is white or black. The measuring distance range from 1mm to 8mm and the central point is about 2.5mm.

There is also an onboard potentiometer to adjust the sensitivity. The infrared diode will be emitting the infrared continually when the module is powered ON, when the emitted infrared light has not been reflected or the strength is not big enough, the receiver diode will in the off state and output pin i.e. DO will be LOW.

Product Details:

1. You can also use the IICLCD1602 LCD to display voltage.
2. By 3P connector, connect this module with the expansion of board Arduino
3. Voltage input range: DC 0-25 V
4. Voltage detection range: DC 0.02445 V  to 25 V
5. Voltage analog resolution : 0.00489 V

This is a simple but very useful module which uses a potential divider to reduce an input voltage by a factor of 5. The Voltage Detection Sensor Module 25V allows you to use the analog input of a microcontroller to monitor voltages much higher than it capable of sensing.

For example with a 0-5V analog input range, you are able to measure a voltage up to 25V. The module also includes convenient screw terminals for easy and secure connection of a wire.

This module is based on the principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller. Arduino analog input voltages up to 5 v, the voltage detection module input voltage not greater than 5Vx5=25V (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V).

Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.

Note:

Keep in mind, you are restricted to voltages that are less than 25 volts.   More than that and you will exceed the voltage limit of your Arduino input.

1. Output Interface: “+ ” connected 5/3.3V, “-” connected GND, “s” connected Arduino AD pins
2. DC input interface: red terminal positive with VCC, negative with GND
3. You can also use the IICLCD1602 LCD to display voltage.
4. By 3P connector, connect this module with the expansion of board Arduino, not only makes it easier for you to detect voltage battery.

Product Details:

You can use this A88 Metal detector non-contact metal induction detection module as a metal detector. When it approaches any metal, it makes a sound.

This is a module specifically designed to detect metal. The module operates by inducing currents in metal objects and responding when it occurs. A nice onboard buzzer signals when it detects something and an onboard potentiometer allow adjustment of sensitivity.

The power cables of the Metal detector non-contact metal induction detection module will need soldering on for the module to function, positive to the outside of the module and negative between the potentiometer and an electrolytic capacitor.

Features :

1. V+ Connect to power positive
2. V- connect to power negative
3. Adjust the potentiometer, let the modules work normally.
4. Small and easy to use module.
5. It comes with a Buzzer for metal detection indication.
