Adafruit SEN54 or SEN55 Adapter Breakout - STEMMA QT / Qwiic
·
The Adafruit SEN54/SEN55 Adapter Breakout lets you quickly connect a Sensirion SEN5x environmental sensor node to any microcontroller or single-board computer via STEMMA QT / Qwiic — no soldering or breadboarding required. The adapter handles the SEN5x's special cable connection and 5 V power req...
Gravity: Arduino Alcohol Sensor (MQ3)
An analogue alcohol gas sensor based on the MQ-3 probe, designed for use with Arduino and other microcontrollers. The sensor outputs a voltage proportional to the concentration of alcohol vapour in the surrounding air, making it suitable for breathalyser-style projects, air quality monitoring, an...
Gravity: I2C ADS1115 16-Bit ADC Module (Arduino Raspberry Pi Compatible)
DFRobot I2C ADS1115 16-bit ADC module can accurately collect and convert analog signals. Through this ADC module, Raspberry Pi can easily use a wide range of Gravity series analog sensors to measure various signals, and perceive this world.Raspberry Pi is a common master control board which is...
Alcohol Gas Sensor - MQ-3
The MQ-3 is an alcohol gas sensor suitable for detecting alcohol concentration in the air, similar to a breathalyser. It provides an analog resistive output based on alcohol concentration, with high sensitivity and fast response time. The drive circuit is simple — just one resistor is needed, and...
Octopus MG811 CO2 Gas Sensor
Octopus MG811 CO2 Gas Sensor is a CO2 electronic brick in our OCTOPUS series, the basic design for the outlook, PCB fixing holes and connections are the same with them.The higher the CO2 concentration is, the lower the output voltage would be. The users can read the CO2 value easily after checkin...
Carbon Monoxide Sensor - MQ-7
This is a simple-to-use Carbon Monoxide (CO) sensor, suitable for sensing CO concentrations in the air. The MQ-7 can detect CO-gas concentrations anywhere from 20 to 2000ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circui...
Gravity: Arduino CO2 Gas Sensor
The Gravity CO2 Gas Sensor uses an MG-811 electrochemical sensing element to detect carbon dioxide concentration in the air. The output voltage decreases as CO2 concentration increases, and an onboard potentiometer lets you set a threshold for a digital on/off signal output. An onboard heating c...
Force Sensitive Resistor 0.5
This is a force sensitive resistor with a round, 0.5" diameter, sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be ...
ELECFREAKS PlanetX CO2 Sensor
·
The gas sensor is an essential sensor for environmental detection. The ELECFREAKS PlanetX CO2 Sensor is designed to detect the concentration of CO2 with high sensitivity. The higher the concentration of CO2 is, the smaller the output voltage value will be. At the same time, it can eliminate the i...
Stackable Header - 5 Pin
This is a 5-pin female header, with extra long legs Pins are spaced by 0.1".
Long Flex sensor
·
This sensor can detect flexing or bending in one direction. They were popularized by being used in the Nintendo PowerGlove as a gaming interface.These sensors are easy to use, they are basically resistors that change value based on how much they're flexed. If they're unflexed, the resistance...

Flex Sensor 2.2
A simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove. I love the Nintendo Power Glove. It’s so bad! The resistance of the flex s...
F1031V Mass Air Flow Sensor
F1031V Mass Air Flow Sensor adopts thermodynamic principle to detect flow rate of gas medium in the flow channel, with high precision and good repeatability. It comes with built-in temperature sensor to provide temperature compensation for measured data. Meanwhile, the sensor has liner analog vol...
Ammonia Gas Sensor - MQ-137
The MQ-137 is an ammonia (NH3) gas sensor from Winsen, designed to detect ammonia concentrations in the air. The sensing element is tin dioxide (SnO2), which has lower conductivity in clean air and increases in conductivity as ammonia gas concentration rises. A simple voltage divider circuit can...
