4 way 5V relay module for Arduino

5V relay module for Arduino and other microcontroller projects

This module has 4 x 5V changover relays with the option of using them through optocouplers. There is an LED for each relay to indicate when it has been activated.

The relay allows the low current microprocessor outputs to switch higher currents and voltages. With the optocouplers it fully isolates the live side of the relays from your microprocessor, this will require a seperate 5V supply to power the relays.

Trigger voltage : 5VDC

Supply Voltage : 5VDC (only needed if using optoisolators)

AC Switch ratings : 250V 10A

DC Switch ratings : 30V 10A

Size 73x52mm

PIR Sensor Module for Arduino

PIR sensor module for Arduino and other microcontroller projects

The HCSR501 is a PIR (Passive Infra-Red) sensor that can detect the presence of people by measuring the infrared radiation radiated by the body. It can be used in a vast and diverse number of projects, including but not limited to: automated lighting systems, burglar alarms, automated door systems, etc.

Principle of operation
All objects with a temperature above absolute zero (0 kelvin) emit electromagnetic radiation. The higher the temperature of the object, the smaller the wavelength of the radiation emitted. The normal human body temperature is 37°C (310.2 kelvin) and it therefore emitts infrared radiation (mostly at a wavelength of 12µm). The PIR sensor can sense when a person has walked into its field of view by measuring the difference in the infrared radiation received from the ambient environment and the human body.

Voltage : 5-20VDC

Power Consumption: 64mA
Logic output: 3.3V
Range: 7 metres, (<120°)
Lock Time: 200 miliseconds
Operating temperature range: between -15°C and 70°C

L298N Motor Driver Module

This is a L298N-based motor driver module capable of accepting a logic input from an Arduino (or a similar microcontroller) in order to control bipolar stepper motors or DC motors. The module has screw terminal connectors for power input and output and a 6 pin header connector for logic input and motor control.

Connecting the jumper links (from ENA and ENB to 5V) allows the motors to spin at full speed, while removing them will stop the motors (unless the ENA and ENB pins are connected to the Arduino for PWM speed control).

Voltage : 5VDC

Logic current: 0mA - 36mA

Size: 43mm x 43mm x 27mm
