The Micro-Voltage Sensor is used to measure voltage within -60mV to 60mV. It amplifies the input voltage in order to measure voltage in micro level.
Milli-Current Sensor is used to measure the current within -20 to 20mA in circuit. When current passes through resistor, it will form a tiny electric potential difference at both ends of the resistor. After circuit amplifying, it can accurately measure the current in circuit.
Microphone collects sound signal using to electret microphone. The microphone consists of dust gauze, shell, vibrating diaphragm, spacer, back plate, copper ring, cavity and PCB. The microphone is formed to a capacitor with vibrating diaphragm, spacer and back plate. There are charge on the plastic vibrating diaphragm. Once it is affected by sound, the diaphragm starts vibrating so that distance between diaphragm and back plate changes. The difference Δd is generated. According to C=εS/4πkd, the capacitance will be changed by ΔC. According to C=Q/V (Q is electric charge quantity), due to the change of ΔC, Q is constant so that voltage will change by ΔV. The sound signal is transfer to electric signal. Sensor circuit transfer the electric signal into analog signal under standard range.
Used to measure the temperature of the surface of the object, gas, non-corrosive acid and alkali liquid.
