Wireless Water Level Control System Expert
Budget: ₹37,500 – ₹75,000 INR
We are an electrical automation company based in India and already have an existing automatic water level controller with motor protection. The current product is wired.
We are now developing a wireless version where the long sensor wires between the terrace water tank and the controller are replaced by RF communication.
Current objective:
We are NOT looking for cloud development right now.
We are looking for an RF / embedded hardware expert who can guide us in prototype-stage development.
Scope of work:
* Review our current wireless product concept
* Advise on transmitter and receiver architecture
* Guide us on 433 MHz / sub-GHz RF approach
* Help in prototype PCB strategy for testing
* Guide on antenna placement, range validation, and communication reliability in multi-floor residential buildings
* Help us with practical next steps for prototype and testing
* If suitable, support further in firmware/hardware decisions
Important:
* This is mainly a residential/building-use product in the first phase
* We already have an existing working wired controller and tank sensors
* Our goal is only to remove the long sensor wires using wireless RF communication
* We have already purchased some RF sample modules from China for evaluation
* We are currently in prototype and range-validation stage
Preferred experience:
* Sub-GHz / 433 MHz RF systems
* Embedded hardware
* RF modules / wireless sensor products
* CC1101 / LoRa / FSK / GFSK / RF transceivers
* PCB bring-up and range testing
* Residential/building wireless applications preferred
Please respond only if you have real hands-on experience in RF / embedded hardware products, not just generic software or networking background.
In your proposal, please mention:
1. Relevant RF / embedded projects you have worked on
2. Whether you have worked on 433 MHz or sub-GHz systems
3. Whether you can support at prototype and advisory level
4. Your expected charges for consultation / project support
