Gaz / Volatile
This temperature & humidity sensor provides a pre-calibrated digital output. A unique capacitive sensor element measures relative humidity and the temperature is measured by a negative temperature coefficient (NTC) thermistor. It has excellent reliability and long term stability. Please note that this sensor will not work for temperatures below 0 degree.
The Grove - Gas Sensor(MQ5) module is useful for gas leakage detecting(in home and industry). It can detect LPG, natural gas, town gas and so on. Based on its fast response time. measurements can be taken as soon as possible. Also the sensitivity can be adjusted by the potentiometer.
he Grove - Gas Sensor(MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer.
Alcohol sensor is semiconductor sensor for alcohol detection. It has good sensitivity and fast response to alcohol, suitable for portable alcohol detector.
Sensor is to create Digital (Lo Pulse) output to Particulate Matters (PM). Lo Pulse Occupancy time (LPO time) is in proportion to PM concentration. The output is for PM whose size is around 1 micro meter or larger. We can use the sensor to detect the dust in clean room.
This sensor provides temperature and humidity data with a quite good sensibility in a serial format thanks to its built-in micro-controller.
High-humidity sensor, usefull for weather appliances.
Large and high quality 1-wire temperature and humidity sensor.
Simple flame sensor
Digital high precision temperature & humidity sensor
Simple smoke sensor with relay output. You only get HIGH or LOW, you can also use it to get some higher current in your circuit when the sensor is activated.
The Sharp Optical Dust Sensor (GP2Y1010AU0F) is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems.
The dust sensor module DSM501A is low cost,compact size for a particle density sensor.
The DHT-22 is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn't require extra components so you can get right to measuring relative humidity and temperature.
Want a more intuitive and tangible timer for your project? This mechanical timer is a quick, easy and inexpensive way! Compared to digital ones, mechanical timers require no programming and won’t lose any settings to unexpected power-off. This is a ubiquitous part inside each kitchen timer or fan, so it takes you no trouble to learn. Just twist the dial...
New DHT11 Digital Temperature And Humidity Sensor Moudle Probe For Arduino
The Analog CO/Combustible Gas Sensor(MQ9) module is useful for gas leakage detecting, it used the sensitive material SnO2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by 1.5V). The sensors conductivity is more higher along with the gas concentration...
MS1100 P111 VOCs Formaldehyde Gas Sensor Module
This is upgradation version of DHT-11 humidity temperature sensor, fully downward compatible, more precise and add I2C interface.
Anemometer/360 Degree Wind Speed Sensor
With its size, it is probably one of the best sensor in terms of accuracy, especially considering it has an output in μg/m3 directly. There is an USB Uart converter included if you want to use it on a raspberry pi or on a computer, but you can always use the digital or uart output directly.
