Product description S1013Y is a miniature metal oxide semiconductor gas sensor based on MEMS micro-hot plate technology for the detection of formaldehyde in the air. The production of the sensor combines MEMS silicon substrate technology, thin film technology, thick film technology and metal packaging technology. When the sensor is in a polluted gas environment, the conductivity of the sensor changes with the concentration of the detected gas in the air. The higher the concentration of the gas, the higher the conductivity of the sensor. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the concentration of the gas. Detection gases: ammonia, hydrogen, alcohol, carbon monoxide, methane, propane, glycine, styrene, propylene glycol, phenol, toluene, ethylbenzene, xylene, formaldehyde, cigarettes, burning smoke, Etc. Factory characteristic gases: ethanol, formaldehyde: 0-10ppm; Features: ➢ ➢ ➢ ➢ ➢ ➢ ➢ high sensitivity to formaldehyde (0 to 10 parts per million (PPM) fast response (~ 15 SEC.) very low power consumption (40 ~ 45 mw) ultra-small size (3.8 mm x 3.8 mm x 1.5 mm) long life (~ 5 years) long-term stability reflow welding can be performed Main Applications: ➢ analysis of formaldehyde in civil, industrial, and environmental protection ➢ The Internet of things, wearable devic

1) Warm-up time If the sensor is stored for a long time without being energized, its resistance will produce a reversible drift. Before use, the sensor needs to be preheated to achieve an internal chemical balance. The preheat voltage is consistent with its heating voltage VH. The storage time and corresponding warm-up time are as follows: 2) Sensor calibration The precision of the sensor is affected by the difference of reference resistance, sensitivity, temperature, humidity, interfering gas, aging time and other factors, and its input-output performance is nonlinear, hysteresis and nonrepeatability....

Sensitivity R g/Ro R g in the figure represents the resistance value of the sensor in different concentrations of gas; R0 represents the resistance of the sensor in clean air Structure diagram Package outline:

Pins 2 and 3 of the sensor are connected to the heating circuit, and pins 1 and 4 are connected to 0.05 the measurement circuit; on the 01.50 premise of meeting the electrical performance requirements of the 0.0 sensor, heating and measurement can share the same power circuit. 0.10 Description: The VH: DC3V V c: DC3V RL as the load resistance, to prevent damage to the gas sensor, suggested that RL O 10 k or higher. In order to give full play to the performance advantage of gas sensor, the heating circuit can be designed with temperature compensation. If you need a temperature compensation design,...

wrapped up, suppressing the sensitivity of the sensor and irrecoverable. The sensor should avoid being exposed to the places where silicone adhesive, hair spray, silicone rubber, putty or other silicon-containing plastic additives may exist. 1.2 Highly corrosive environment Exposure of the sensor to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, etc.) will not only cause corrosion or destruction of the heating material and sensor leads, but also cause irreversible changes in the performance of sensitive materials. 1.3 The pollution sensor of alkali, alkali metal salt and...
