I require a very simple product that has both a transmitter and a receiver. This will be used to wirelessly extend an irrigation system. When the Irrigation System starts a watering program it outputs 24V to the terminals which then powers a solenoid to water the lawn. At the end of the program the power is stopped and the solenoid is closed. The transmitter will be connected to those terminals to receive the 24V power on start of program. This will trigger a signal to be transmitted to the receiver that will then trigger a relay. The required power for the solenoid will be connected to the relay. The relay will need to be capable or 5v to 240v. The receiver will need external power - 24v I will also require the Tx and Rx to be assignable as pairs (max 99 pairs required). This Tx and Rx need to ultimately be produced as cheaply as possible.

Hello, I'd like to help you with the project. Could you write what distance should cover this wireless extender? The production price will be vary from this. I can use 433MHz transmitter - receiver pair or 2.4GHz transmitter module. My bid include developing of circuit diagram, firmware and a prototype on a breadboard. I will provide a video of testing, circuit diagram and a firmware. I'd like to use cheap MCU Microchip. If you need to receive the prototype, than the prototype PCB, all parts and shipping should be paid separately. Let me know if you are interested.

We can design the product you specified using available, cheap but reliable and addressable RF modules. We will provide a prototype transmitter-receiver pair without extra cost, only shipping from Turkey to your location should be added. If you opt so, we can also manufacture these units in volume. Please note that the bid does not include end-product specific issues such as custom case/molding design and CE or other certification. However, without any extra cost, we can enclose the transmitter and receiver in readily available plastic project boxes so that they are not affected from water. I have a PhD degree in Electrical and Electronics Engineering from one of the most reputable universities in Turkey and have 15 years of microcontroller based systems design experience (both hardware and firmware) and 5 years of RF design experience. I am founder and manager of an R&D company focusing on analog and embedded systems design.
