37 in 1 Sensors Kit compatible with Arduino
Arduino Uno R3 Starter Kit
HC-SR 04-Ultrasonic Range Finder
Infrared Obstacle Avoidance IR Sensor Module- Good Quality
MQ 135 Air Quality/Gas Detector Sensor Module For Arduino
MQ-6 Liquefied Petroleum Isobutane Propane Gas Sensor module
- Operating Voltage: 5V DC
- Indication of the signal output
- Dual signal output (analog output, and TTL level output)
- 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage
- High sensitivity to hydrogen
- Can be resistant to ethanol steam, LPG (petroleum), smoke interference
- Has a long life and reliable stability
- Fast response and recovery characteristics
PIR Motion Sensor Detector Module HC-SR501
- Automatic induction: to enter the sensing range of the output is high, people leave the sensing range is automatically delayed off high, output low.
- Photosensitive control (optional, not factory setting) can be set photosensitive control, day or light intensity without induction
- Two kinds of trigger modes: (jumper selectable), Working voltage range: DC 4.5-20V, Power Consumption: 65mA, TL output: 3.3V, 0V
- Unrepeatable trigger: the sensor output high, the delay time is over, the output automatically from high into low
- b - Repeatable trigger: the sensor output high, the delay period, if there is human in its sensing range Activities, the output will remain high until after the delay will leave high to low
