Very loud car horn with about 36 watts of power, powered by 12 volts. It emits sound at the level of 110 dB. Due to the high current consumption, appropriate amplification should be used when controlling it from the microcontroller. A transistor amplifier or relay can be used for this purpose. The siren can be powered from e.g. lithium-polymer packs with a nominal voltage of 11.1 V.
- Supply voltage: 12 V
- Volume: 110 dB +/- 5 dB
- Current consumption: up to 3 A
