PIC16F88 RF Remote 433MHz Transceiver Switches

There are all the source files of the project, which was controlled by a 1000 watt water pump with the switch circuit working with the RF communication system. UHF Remote Mains Switch Do you want to remotely turn the main devices on and off? This UHF Remote Mains Switch can do that for you. It is powered using a handheld UHF transmitter, or you can use it with the Water Tank Level Meter Base Station announced last month to automatically control mains powered water pumps. A built-in timer also allows the unit to turn off automatically after a preset time.

There are many situations where it would be appropriate to turn a device on or off remotely rather than manually. Such situations include turning on the road lights when you get home, turning the garden and/or pool lighting on and off, and turning on the power to the water pumps.

Remote switching can also be very convenient for devices that are difficult to access, for example in a factory. Click for larger image UHF Remote Mains Switch can switch loads up to 1875 W or 2500 W

This unit was originally designed to turn on and off mains powered water pumps in response to signals transmitted by the Water Tank Level Meter Base Station announced last month. However, we soon realized that by adding a separate handheld transmitter to control the unit, it could also be used as a standalone unit for many other applications.

It’s really simple – you don’t need a handheld transmitter if you want to team the unit with the Water Tank Level Meter Base Station. This is because the Base Station has a transmitter built into it. Conversely, you need the transmitter to use the unit in other applications – ie without the Base Station.

Meanwhile, commercial remote electrically operated switches are readily available for switchgears rated up to 1000W. A typical example of these is the Altronics Cat. The A-0340 can be used with up to five outputs and has a range of 20m.

However, if you want to replace appliances above 1000W or control water pumps, you need the UHF Remote Mains Network described here. It can replace devices rated up to 2500 W at a range of up to 200 m. That’s 10 times the range typically found in low-cost commercial units!
