Figaro TGS 816 Product Information Sheet
The TGS 816 is a general‑purpose semiconductor gas sensor that responds to a wide range of combustible gases, especially methane, propane and butane. Its tin dioxide (SnO₂) sensing element changes conductivity in the presence of target gases, allowing simple circuits to convert this change into an output signal. The sensor’s ceramic base can withstand temperatures up to 200 °C, making it suitable for domestic gas leak detectors, portable detectors and industrial safety applications.
Technical data include a measurement range of 500‑10 000 ppm, heater voltage of 5.0 ± 0.2 V (DC/AC), heater power consumption of about 835 mW, and a sensor resistance at 1000 ppm methane of 5 kΩ ~ 15 kΩ. Standard test conditions are 20 ± 2 °C and 65 ± 5 % RH, with a circuit voltage of 24 V (AC/DC). The sheet also provides dimensions, pin connections, and typical sensitivity curves for temperature and humidity.

Questions answered in Figaro manuals
What resistor values should be used in the basic circuit?
Use R1 = 1.2 kΩ, R2 = 1.2 kΩ and VR = 100 Ω as recommended.
How is a sensor fault detected electrically?
A fault is indicated when the output voltage drops to 0.2 V or lower (Vout ≤ 0.2 V).
What is the operating temperature range for the EC01 chamber?
The chamber can be used between 0 °C and 50 °C.
From: Figaro EC01 Gas Sensor Evaluation Test Chamber User Manual
How can the power supply voltage be adjusted?
Insert a screwdriver into the voltage adjustment hole on the control box and turn the knob to set the voltage between 4.00 V and 5.50 V.
From: Figaro EC01 Gas Sensor Evaluation Test Chamber User Manual
What heater voltage is required for the TGS 832?
The heater should be powered with 5 V ± 0.2 V (DC or AC).
How is the sensor’s output obtained in a basic circuit?
When the sensor is connected as shown, the voltage across the load resistor (V_RL) increases as the sensor resistance (Rs) decreases with higher gas concentration.
