Working voltage is 3V, use two batteries 

Transmission distance is about 50 m

A normal new battery can work continuously for about one week! 

This product has a high sensitivity! You can hear very faint sounds, like silent ticking clocks.

This product uses FM modulation, you can use FM radio reveive signals. You can also use your phone's wireless connection or car radio for reception!

Microphone is built into the product, the cable is like an antenna , the switch is in the process except you can put it off when you do not want it to work so that it can increase battery efficiency!

  It is a relay switch module. It can automatically detect ambient sound and light intensity. When the sound exceeds the set threshold, the relay automatically closes, delays for a certain time and then switches off. 

Remote control of appliances via 433Mhz RF signal. The receiver can be programmed for various switching modes. By default, this is set so that when I press a button on the transmitter, the receiver is active as long as the button is pressed. If you stop pressing the button, the relay on the receiver must also be switched on exactly.

ELIDE FIRE is enough in case of fire just throw in the fire. The device is activated itself when contactwith an open fire and the flames are reliably extinguished.

ELIDE FIRE effectively and immediately extinguishes fires of solids, flammable gases, flammable liquids and electrical equipment (fires of type A*, B*, C*, E* ).

A PWM signal generator is a device that provides electrical signals at different levels of frequencies, square waves and outputs. 

It is used as a signal source or wake-up source for testing. Widely used in manufacturing practice and technology.

FUNcube Dongle Pro + has the same design objectives as the original FUNcube Dongle, but we have taken into account many comments on the original FCD and have improved both performance and functionality. Although it may look similar from the outside, it's a whole new design.

In terms of performance, we have added 11 discrete hardware filters to the front, including narrow SAW filters on amateur 2m and 70cm bands. This has a hugely beneficial effect on blocking the front-end, especially on the VHF.

There is also a new LNA used with much better performance, which improves OIP3 to 30dBm (around 10dBm). In addition, the rf grades are at 3.15 V compared to the original 1.5 V FCD, which significantly increases the dynamic range.
