LC 5A 12V Overcurrent Protection AC Current Detection Sensor Module uses a current transformer to collect the AC signal to achieve the relay over-current signal output within 0-5A. Relay pull while over-current, relay released while not over-current. Users can use the relay COM; NC, NO three ports to control the external circuit on and off, in order to achieve over-current protection.
Functions:
- Current detection resolution can change the parameter of resistance parameters;
- Output over-current switching signal output;
- The over-current signal setting critical point adjustable.
Using Instructions:
- Measured the wire through the current transformer, connect VCC and GND to the DC12V power supply;
- Adjust the potentiometer, when you hear the sound of the relay pull (can be measured with a multimeter COM and NO whether was turned on; is connected to the relay means activated), then reduce or cut off the current flowing that through the tested wire; if the relay release at this time that over-current protection point has been identified (available to multimeter COM and NC measurement whether is connected; is connected to the relay means it release);
- When reduce or cut off the current flowing through the wire; the relay is not released, will still need to continue to adjust the potentiometer to find the over-current protection point.
Package Includes:
1 x 5A 12V Overcurrent Protection AC Current Detection Sensor Module.

A closed loop current sensor consists of a Hall sensor mounted in an air gap of a soft magnetic core, a coil wound around the core and a current amplifier. The current carrying conductor placed through the aperture of the sensor produces a magnetic field that is proportionate to the current.
Closed-loop sensors measure AC and DC currents and provide electrical isolation. They offer fast response, high linearity, and low temperature drift. The current output of the closed-loop sensor is relatively immune to electrical noise.

This SmartElex RLS-06 Analog & Digital Line Sensor Array has 6 IR LED/phototransistor pairs, making it a great detector for a line-following robot. Each sensor has its own digital and analog output. potentiometer to adjust the sensitivity of the individual sensors.
The TCRT5000 reflectance sensors array is intended as a line sensor, but it can be used as a general-purpose proximity or reflectance sensor. The module is a convenient carrier for eight IR emitter and receiver (phototransistor) pairs evenly spaced at intervals.
Each phototransistor is connected to a pull-up resistor to form a voltage divider that produces an analog voltage output between 0 V and VIN (which is typically 5 V) as a function of the reflected IR. The lower output voltage is an indication of greater reflection.
The outputs are all independent, but the LEDs are arranged in pairs to halve current consumption. The LEDs are controlled by a MOSFET with a gate normally pulled high, allowing the LEDs to be turned off by setting the MOSFET gate to a low voltage. Turning the LEDs off might be advantageous for limiting power consumption when the sensors are not in use or for varying the effective brightness of the LEDs through PWM control.
Building a line following robot for a school project or competition Or building an Automated Guided Vehicle (AGV) for industrial use Maker Line is the right sensor for you. With 5 x IR sensors array, it is able to track lines from 13mm to 30mm in width. Line color is selectable as light (White) or dark (Black) line.
The sensor calibration is also simplified. Adjusting the potentiometer for each IR sensor is not needed anymore. Instead, press the calibrate button for 2 seconds to enter calibration mode, sweep the sensors array across the line, press the button again and you are done. The calibration data is saved in EEPROM and it will still be intact even the sensor has been powered off. Thus, Calibration only needs to be carried out once unless the sensor height, line color, or background color has changed.
Maker Line also supports dual outputs: 5 x digital outputs for the state of each sensor independently which is similar to the conventional IR sensor, but you get the benefit of easy calibration; One analog output where its voltage represents the line position. Analog output also offers higher resolution compared to individual digital outputs. This is especially useful when high accuracy is required such as building a line following robot with PID control.
RedBot Sensor – Line Follower is an add-on for the RedBot that gives any robot the ability to detect lines or nearby objects. The sensor works by detecting reflected light coming from its own infrared LED. By measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or even objects directly in front of it. The sensor has a 3-pin header that connects directly to the RedBot Mainboard via female-to-female jumper wires. Use the included RedBot library to detect lines or objects.
This version of the SparkFun Line Sensor Breakout – QRE1113 (Analog) features an easy-to-use analog output, which will vary depending on the amount of IR light reflected back to the sensor. This tiny board is perfect for line sensing applications and can be used in both 3.3V and 5V systems. The board’s QRE1113 IR reflectance sensor is comprised of two parts – an IR emitting LED and an IR sensitive phototransistor.
When power is applied to the VCC and GND pins the IR LED inside the sensor will illuminate. A 100Ω resistor is on-board and placed in series with the LED to limit current. A 10kΩ resistor pulls the output pin high, but when the light from the LED is reflected back onto the phototransistor the output will begin to go lower. The more IR light sensed by the phototransistor, the lower the output voltage of the breakout board.
