or you can even try the 20W amplifier

we now have rugged metal buttons with a full colour RGB LED ring light

Please note: This sensor is sensitive to CO ( ~ 1 to 1000 ppm)

Water-proof Ultrasonic Sensor _MAKE_POWER_PSU Note: Not compatible with theMost ultrasonic distance sensors aren't waterproof which can be a problem if you need your project to withstand the elements outdoors. No need to worry anymore! We have developed waterproof ultrasonic distance sensors with a waterproof sealed emitter. This sensor is suitable for outdoor applications such as car reversing sensors, security alarms, industrial inspection, etc. What will you make? Specification Operating Voltage: 5V DC Static Current: 5mA
