Synapse rf200pf1 - embedded python microcontroller
HY-SRF05 - Ultrasonic sensor - [url removed, login to view]
5v 2 channel relay module - [url removed, login to view]
breakout board - [url removed, login to view]
Provide wiring/assembly instructions and python scripting to achieve these outcomes
Use ultrasonic sensor to turn relays on and off at certain thresholds. Logic works like this
When Height gets to (30cm) then close relay 1 then (5 minutes) later close relay 2. Open both relays once height drops to (200cm) - turning everything off. BRACKETS ARE ADJUSTABLE VARIABLES THROUGH PORTAL.
Once a working prototype is produced I will change to using this ultrasonic sensor

So necessary changes will need to be included so I can change at a later date.
I already have the above hardware on hand so please don't say use a arduino board etc.
The rf200pd1 uses a stripped down python script called "snappy" which if your not familiar with you will need to do some research on. The synapse products have the ability to be configured via their built in mesh network and have a program called portal which can be used to change the variables I have put in brackets in the above logic.
This project may lead to more similar work.

i can do this project using a pic controller its more easier, i have already interfaced this sensor with a pic (see my portfolio). i can complete it within 4 days.
Hello..Im Electrical-electronics Engineer..I have experience about the microcontroller suppported circuits desing..If you contact with me i can solve this work for yoU..
