Electric fences: every section reports its voltage.
The Fence Control sensor measures the voltage on the wire and reports a drop promptly, with the section that caused it. Proven on 800 km of protective fence in Kenya, suited to pastures too.
- Voltage 5,900V
- Target ≥ 8,000V
- Section 180m
What goes wrong quietly.
Drops nobody sees
A branch on the wire, wet grass after rain, a cracked insulator: the voltage sinks and the fence stops protecting. Until someone drives the line, nobody knows.
Too much fence for one round
A reserve perimeter or a summer pasture is kilometres long and far from the road. The inspection round takes a day, and it is the same day whether something is wrong or not.
No proof after the incident
When an animal breaks out or a predator gets in, the questions come: was the fence live, since when not, who knew. A logbook cannot answer that.

- Voltage 5,900V
- Target ≥ 8,000V
- Section 180m
Yes. Fence voltage dropped to 5,900 V in the northwest section, significantly below the target range. The affected area is approximately 180 m long.
Inspect the northwest fence section for vegetation contact, damaged insulators or a broken wire.
Would you like me to investigate further?
Looking closer. This is what the data shows:
Possible reasons- The drop began at 19:52, right after the evening wind picked up.
- The two neighbouring sections hold their voltage, so the fault is local.
- The last inspection of this section was 6 weeks ago.

- Voltage 6,400V
- Yesterday 18:00 8,900V
- Rain overnight 31mm
Most likely vegetation. The south section fell from 8,900 V to 6,400 V in step with 31 mm of rain overnight, while the dry sections held their voltage. Wet grass and branches on the wire are draining the pulse to ground.
Schedule clearing of the river section this week. Until then, expect the voltage to recover as the vegetation dries.
Would you like me to investigate further?
Looking closer. This is what the data shows:
Possible reasons- The drop tracks the rain curve from the weather station, not a single moment.
- The same section showed the same pattern after the last two rain events.
- The section runs along the river bank, where growth is fastest at this time of year.

- Voltage 2,100V
- Minimum for cattle ≥ 3,000V
- Below since 4h
No. The upper paddock has been at 2,100 V for 4 hours, below the 3,000 V that cattle respect. The lower paddock on the same energiser is fine, so the fault is most likely between the two gates.
Check the east gate first: the handle may not be back on the wire. Count the cattle while you are there.
Would you like me to investigate further?
Looking closer. This is what the data shows:
Possible reasons- The voltage dropped in one step at 01:40, not gradually, which points to a break or a fallen wire.
- There was no rain and no wind at that time.
- The gate contact on the east side reported an opening at 01:38.

Where the sensors sit.
Every dot is a sensor family in its typical place. Select one to see what it measures and what baiond does with it.
A Fence Control sensor sits on each section and measures the voltage on the wire itself, not at the energiser. The readings travel by LoRaWAN to the baiond Gateway, so a fence far from mains and mobile coverage still reports. The Space System knows which sensor guards which section, and when a value leaves its range the ranger or farmer gets a message naming the section, the drop and the likely cause. Every event is logged with a timestamp, so the fence history is there when insurers or authorities ask.

The energiser is where the whole fence starts. Output voltage, mains supply and the earth return are measured here, so a weak pulse is spotted at the source and not on a patrol days later.
Sensor page: Energy -
A contact on the gate reports every opening with time and duration. Left open after the evening round, it raises a message, so the gap can be closed early.
Sensor page: Presence & Access -
Branches and wet undergrowth short the wire after every storm. The fence sensor on this section reports the voltage drop on its stretch, so the team knows which section to check.
Sensor page: Electric Fence Sensor -
Where the fence crosses the river, high water and debris pull the wire down. The sensor shows the crossing as its own section, so a flood night is a reading, not a surprise.
Sensor page: Electric Fence Sensor -
Kilometres from the nearest socket, the sensor runs on a small solar cell and its battery. Voltage, battery state and the radio link are reported alongside, so a dead node is a message too.
Sensor page: Custom-built Sensors -
The last sensor before the fence returns to the energiser reads the voltage that actually arrives. The difference to the source is the health of everything in between.

The inner fence that keeps the cattle where they belong. A drop below the herd’s threshold is reported to the farmer’s phone.

The same site, run differently.

The drop reaches the ranger promptly, on his phone.
Wet grass after rain shorts a section every spring.
The pattern shows up in the curve. Cut before it shorts.
"Was the fence live?" – a question with no answer.
Every drop and every recovery logged with the time. Proof on file.

Your industry guide
One PDF for your industry: the questions baiond answers there, the sensors that measure it and what changes on site.
What managers ask before they start.
How does the sensor measure the fence voltage?
It clamps onto the live wire of a section and measures the pulse voltage there, not at the energiser. That is why it sees a fault on the line that the energiser display would still hide.
Does it need power or mobile coverage on the fence?
No. The sensor runs on its own battery, optionally with a small solar cell, and sends by LoRaWAN over long distances to the baiond Gateway. Only the gateway needs power and a connection.
What does an alert look like?
A message on your phone or in the dashboard with the section, the current voltage, the target range and how long the drop has lasted. You can ask baiond why, and the answer comes with the readings and a recommendation.
Does this work for a pasture fence as well as a reserve?
Yes. The sensor does not care whether the wire keeps rhinos in or cattle. A summer pasture with three sections needs one gateway and three sensors; a 800 km perimeter needs the same parts, more of them.
Can baiond tell vegetation from a broken wire?
It narrows it down. A slow drop after rain that recovers in the sun points to vegetation, a sudden drop to zero on one section to a break or a lost insulator. baiond names the likely cause with every alert; you still inspect, but you know where and what for.
Is the history usable for an insurance claim?
Every drop, every recovery and every alert is stored with a timestamp per section. You export the period in question as a report and attach it.
