Smart Electronics Hydrogen sulfide sensor probe MQ-136 Toxic gas H2S sensor MQ136

Hydrogen sulfide sensor probe MQ-136 Toxic gas H2S sensor MQ136 The gas-sensitive material used in the MQ136 hydrogen sulfide gas sensor is tin dioxide (SnO2) with low conductivity in clean air. When there is hydrogen sulfide gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of hydrogen sulfide gas in the air increases. Using a simple circuit, the change in conductivity can be converted into an output signal corresponding to the gas concentration.

Smart Electronics High density distribution plantar pressure sensor, resistor type sensor FSR pressure acquisition weight sensor

High density distribution plantar pressure sensor, resistor type sensor FSR pressure acquisition weight sensor Film pressure sensor is piezoresistive, also known as resistive, equivalent to varistor in the circuit. When the sensor has no external load, the circuit is in high resistance state (generally greater than 2m Ω). When the external pressure is applied to the sensor, the circuit resistance will decrease (tens of K Ω or less). With a multimeter, the resistance value can be read directly by connecting to two external terminals. The resistance value changes with the change of external pressure. The voltage is inversely proportional to the resistance, while the voltage カ is linearly related to the conductivity, so the pressure change can be inversely deduced according to the conductivity change.

Smart Electronics Thin film pressure sensor, Square 16 nodes side length 20 mm flexible resistive motion sensor

Thin film pressure sensor, Square 16 nodes side length 20 mm flexible resistive motion sensor The IMM0092 of Idong Film Electronics is a member of the single-node sensor family. Although IMM092 has 16 nodes, because IMM00092 has 32 lines of output, each node has 2 lines of output, and the 16 nodes are independent of each other. They are very reliable piezoresistive sensors. When the pressure (pressure) applied to the effective area of the sensor increases, the output resistance of the sensor decreases. Single-point sensors can be measured using a multimeter or customer's own circuit.
