Percussion knock sensor module for Arduino KY-031
KY031
Percussion knock sensor module for Arduino and other microcontroller projects
This module is a switch that will detect being hit, it is not as sensitive as the vibration switch (KY-002) so can be used in projects that may be moving and an impact needs to be detected. This sensor acts like a switch that will "make" when the sensor is knocked.
Voltage :upto 5VDC
Size 19x15mm

Photoelectric Smoke Detector with Hush Feature
SMODE
Photoelectric Smoke Detector with Hush Feature
This unit detects smoke with its sensitive photoelectric system and circuit giving an alarm signal as an early warning.
Photoelectric alarms are unlikely to trigger a false alarms from kitchen or bathroom steam than traditional ionization alarms.
This model also has a hush feature reducing sensitivity for a ten minute period when needed
Can be hung on walls & ceilings.
​Runs on 9V PP3 battery (not included). To add battery click here: ALKGP

PIR Sensor Module for Arduino
HCSR501
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 |
