This photo-resistance module is very sensitive to ambient light. Activation of the microcontroller or retransmission modules,
The brightness module of the ambient light reach the set threshold, the output is high when the ambient light exceeds the set threshold.
The DO output can be connected directly to a microcontroller to detect the light environment and create a light control switch.
It has a speed range of 0% to 100%. Digital Light Intensity Sensor with Photo Resistance with LM393 Controller features:
- Operating voltage: 3.3 - 5 V
- Input current: 50 mA
- Use a very sensitive photo resistance
- Use a LM393 wide voltage comparator, high quality output signal
- Adjustable potentiometer can regulate the brightness of detected light

Sound detection module for Arduino projects, smart cars.
Sound Detection Sensor Module features:
- Adjustable High Sensitivity Acoustic Sensor
- Chip LM393
- Red LED indicator integrated

- Power 4 ~ 6V
- Measures 32x16x10mm

Wired Bone Conductor Transducer - 8 Ohm 1 Watt
This amazing speaker does not have a movable cone like most From the speakers you've seen, instead, a small metal rod is wrapped with the voice coil.
When the current is driven through the coil, the magnetic field makes a piece of metal expands and contracts, if pressed against a flat surface or cavity makes it a speaker! Often these size transducers are pressed against the jaw or ear bone to turn the skull into a speaker socket.
The effect is a perfect quality sound that comes from your head and no one else can hear it. You can also press it against your elbow bone and stick a finger in your ear to listen to the audio transmitted through your arm!
