1. Easy to use
2. Color: Black
3. SCL – I2C clock pin, connect to your microcontrollers I2C clock line. Can use 3V
   or 5V logic, and has a 10K pullup to Vin

   5V logic, and has a 10K pullup to Vin
5. Power Pins: Vin – this is the power pin. Since the sensor chip uses 3 VDC for logic, we have
   included a voltage regulator on board that will take 3-5VDC and safely convert it
   down. To power the board, give it the same power as the logic level of your
6. Power Pin: 1V8 – this is the 1.8V output from the voltage regulator, you can grab up to 50mA
   from this if you like
7. GND: common ground for power and logic
8. You can easily wire this breakout to any microcontroller; we’ll be using an Arduino.

The sensing element is comprised of a metal oxide semiconductor layer formed on an alumina substrate of a sensing chip together with an integrated heater. In the presence of a detectable gas, the sensor’s conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration. The TGS 2600 has a high sensitivity to low concentrations of gaseous air
contaminants such as hydrogen and carbon monoxide which exist in cigarette smoke. The sensor can detect hydrogen at a level of several ppm. Due to the miniaturization of the sensing chip, TGS 2600 requires a heater current of only 42mA and the device is housed in a standard TO-5 package

Features:

1. Low power consumption
2. High sensitivity to gaseous air contaminants
3. Long life and low cost
4. Uses a simple electrical circuit

Figaro’s TGS5141 is a battery-operable electrochemical sensor that uses a unique electrolyte that eliminates the need for a water reservoir. By eliminating the water reservoir used in TGS5042, the comparative size of TGS5141 is reduced to just 10% of TGS5042. With its ultra-compact size, this sensor is the ideal choice for size-oriented applications such as portable CO detectors, small residential CO detectors, and multi-sensor fire detectors. OEM customers will find individual sensor data printed on each sensor in barcode form, enabling users to skip the costly gas calibration process and allowing for individual sensor tracking.

Applications:

Residential and commercial CO detectors
Fire detection

Features:

1. Ultra-compact
2. Battery operable
3. High repeatability/selectivity to CO
4. Linear relationship between CO gas
5. concentration and sensor output

1 x Figaro TGS5141-P00 Carbon Monoxide Sensor home air quality monitor

AOX4000 is an oxygen sensor that measures the partial pressure of oxygen in the environment based on the principle of fluorescence quenching. The sensor has a built-in air pressure sensor, which can directly output the values of ambient air pressure, oxygen partial pressure, and oxygen concentration, which is convenient for users to read data intuitively. Compared with electrochemical sensors, AOX4000 has longer life. Due to the temperature compensation function, no additional compensation system is required. AOX4000 is very stable and environmentally friendly, does not contain lead or any other harmful substances.

Features:

1. High precision, temperature compensation
2. No Drift, Low Power Consumption
3. Long life, fast response, fully calibrated
4. Lead-free, RoHS compliant
5. Digital output oxygen partial pressure, atmospheric pressure

Package Includes:

1 x Fluorescent oxygen sensor AOX4000

The LPM2610 is a pre-calibrated module for LP gas alarms which is precisely calibrated in Figaro’s humidity and temperature-controlled facility. The module uses TGS2610-D00 which incorporates a filter to eliminate the influence of interference gases such as alcohol, resulting in highly selective response to LP gas. The most important process in manufacturing reliable residential gas alarms is adjusting the alarm point. Calibration is a complicated and time-consuming process that also requires a substantial investment in calibration equipment. By
eliminating the costly calibration process, this module enables users to easily and simply manufacture residential LP gas alarms. Figaro has taken the complexity out of designing a gas detector circuit by providing users with a temperature compensation circuit that combines a built-in thermistor and individually adjusted load resistor together with Figaro’s low-power LP gas sensor.

1. Factory calibrated * Residential LP gas alarm
2. Temperature compensation circuit
3.  Interferent-resistant sensor TGS2610
4.  Compact size
