Wireless Charging Module 5V/2A
US$16.25
This is a wireless charging module based on “magnetic-coupled resonance” technology that only consumes one-millionth of the power of traditional electromagnetic induction power technology. When the transmitter is electrified, it does not emit electromagnetic waves but forms a non-radiating field magnetic field around it. This magnetic field is used to connect with the receiving end and excite resonance at the receiver, by which the energy can be transmitted with minimal power consumption. Transmitting efficiency can reach up to 90%.

Water-proof Ultrasonic Sensor (ULS)
US$48.75
This is an ultrasonic distance sensor(ULS) of high performance with an enclosed waterproof probe. The sensor, like many other ultrasonic sensors, based on the principle of ultrasonic echo ranging, determines the distance to a target by measuring time lapses between the sending of a pulse and receiving of the echo without contacting. It can be used to detect transparent or non-ferrous objects, metal or non-metallic objects, liquid, solid, powder materials and so on. The unique physical bell-mouth shell of the sensor greatly improves the directivity and stability of its output ultrasound.
