Require Circuit to measure electric fence voltage.
Input is approx 10Kv pulsing at on for several milliseconds once a second.
Circuit is to step voltage down to max 5v (suitable for input to a Arduino)
Sensing circuit to include opto islolation between 10kv input 5v output as well as overvoltage protection.
Given the large range of Energizers available a full wave bridge rectifier should also be included. Consideration to a peak hold circuit that resets every 5 seconds (user selectable on/off/rate).
Focus to given to lowest possible cost of components. All resistors are to be rated to withstand the voltages exposed to at their location in the circuit.
PCB design would also be useful giving consideration to clearances to ensure no tracking between HV input terminals and other components.
No read out display is required in this design.
Device will be permanently connected to the fence, so input impedance should be sufficiently high enough not to be seen as a "short on the fence"
Factor to consider: Small footprint, Low cost components, easily reproduce-able, if active components are required low power consumption. (device will be powered by solar rechargeable battery)
Deliverables include: Circuit diagram, Bill of materials, PCB design, explanatory notes, component cost, proof of functionality.
