TSL2581FN (Ambient Light Sensor-Street Light Control Sunlight)
General Features:
- Features TSL2581FN with ADC, feels the ambient light just like human vision
- I2C interface directly outputs the ambient light intensity value, needs no calibration, less noise interference
- Embedded infrared photodiode, gets high precision output even in environments with strong infrared noise interference
- Features interrupt output, programmable upper/lower thresholds
- Sensitivity is about 30 times higher than TSL2560/TSL2561
- Embedded voltage level translate circuit, allows directly connecting to 3.3V/5V MCU systems
Description
The TSL2581 sensor has two analog-to-digital (ADC) converters that integrate currents simultaneously from two integrated photodiodes. By changing the integration time, both low and high intensity of incident light can be measured. The sensor can be used with any microcontroller equipped with an I2C interface (eg STM32Discovery, Arduino or Raspberry Pi)

DHT22- (Temperature and humidity sensor)
Product description:
The DHT22 module is designed to measure the temperature and humidity of the atmosphere. The difference from the younger model (DHT11), The DHT22 has a wide range and a high precision determination of temperature and humidity. The sensor works on the OneWire bus, which makes it possible to connect it to the Arduino only three wires ( two of which are POwer supply). Low power consumption allows you to install it on stand-alone devices.
MQ-6 LPG Gas Sensor Module
This is a simple-to-use liquefied petroleum gas (LPG) sensor, suitable for sensing LPG (composed of mostly propane and butane) concentrations in the air. The MQ-6 can detect gas concentrations anywhere from 300 to 10000ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.
MQ-7 (Carbon Monoxide Gas Sensor Module)
MQ-7 Carbon Monoxide Gas Sensor Module is used to detect Carbon Monoxide (CO) concentration, it can detect CO-gas concentrations anywhere from 20 to 2000ppm. This sensor has a high sensitivity and fast response time. The module outputs a voltage from 0 to 5V relative to the CO concentration. The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.
