Smart Electronics HC-SR312 Human body sensing infrared sensor PIR infrared module HC-SR312
Technical Parameters1. Working voltage: DC 2.7-12V; 2. Static power consumption: <0.1mA; 3. Delay time:2sec; 4. Blocking time:2sec; 5. Trigger mode:repeatable; 6. Sensing range: ≤100 degrees cone angle, 3-5 meters; (according to the specific lens) 7. Operating temperature: -20 - +60℃. 8.PCB external size:10mm*8mm

9.Module lens: small lens

Functional features

a. Enhanced anti-interference, internal digital signal processing, direct high and low level output.

b. Repeatable trigger mode: that is, after the induction output high level, in the delay time period, if there is a human body

in its sensing range of activities, its output will remain high until the person leaves the delay time, before becoming low level

(that is: the induction module detects each activity of the human body will be automatically postponed after a delay time period,

and the time of the last activity as the starting point of the delay time).

Sound sensor module voice control switch strength detection audio amplifier microphone LM386

The LM386 is an audio integrated power amplifier with its own low power consumption, adjustable gain for updating the internal chain, wide supply voltage range, fewer external components and less total harmonic distortion. It is mainly used in low-voltage consumer products. In order to minimize the peripheral components, the voltage gain is built-in as 20, and by adding an external resistor and capacitor between pin 1 and pin 8, the voltage gain can be adjusted to any value within 200.
