Are you driving out to check your electric fences only to find a fault and your livestock out on the road? The Farmo Electric Fence Sensor gives you real-time voltage readings from any fence line, straight to your phone. With instant alerts the moment voltage drops below your set threshold, you can find and fix faults faster, protecting your livestock, your perimeter, and your time.

1+ Year Battery Life (User Replaceable)
Email & SMS Notifications

A faulty electric fence offers zero deterrent to stock, predators, or intruders. And in most cases, you won’t know about it until the danger is done. The Farmo Electric Fence Sensor is a simple, reliable monitoring solution that keeps a constant watch on the fence line voltage on your home property or remote block. Compatible with any brand or type of electric fence, it records and reports voltage up to 12,000V, and sends you an immediate SMS or email alert the moment readings fall below your custom threshold.

Data Includes

  • Fence Voltage (kV)

Alerts

  • Fence Voltage (kV)

Simply mount the sensor on a post and clip the sensor leads onto your electric fence: one to the hot wire, and one to the ground wire. Once activated in the Farmo App, the sensor continuously measures the voltage on the fence line and transmits the readings to your phone, connecting via long-range NB-IoT/Cat-M1 cellular networks. When voltage drops below your chosen alert threshold, the device sends an instant notification to your phone via SMS or email, so you can act on a fault before it becomes a bigger problem.

How Our Customers Use Farmo to Stay Ahead

Reduce the reliance on frequent physical inspections.

Stop driving the boundary just to confirm your fence is live. Get real-time voltage readings from every monitored line in the Farmo App, so you know the moment something changes.

Stop livestock escaping into neighbouring properties or roadways

Whether it's a downed wire, a weed short, or a faulty energiser, you'll receive an immediate SMS or email alert the moment voltage drops below your set threshold. The unintentional moving of livestock between properties is a biological hazard and management problem leading to poor breeding timing and performance.

Prevent rural crime

Property invasion by criminals stealing livestock often involves cutting fences which electric fence systems can detect and give instant alerts.

Managing rotational grazing and temporary paddocks

When managing rotational grazing and temporary paddocks the Farmo Electric Fence sensor adds value by showing in real time whether those temporary or internal fences are actually working.

The electric fence sensors and water rats have provided peace of mind knowing that the cattle are where they should be and with water in the troughs.
Great customer support when I experienced issues with fence sensors.

jeanette

I had a real problem getting accurate and up to date rain data on our farm in far east Gippsland when I spend most of the time in Melbourne. The rain gauge through Farmo solved the problem and the support and backup with questions was great

Mick

We have been using Water Rats for a number of years to monitor outlying or problem troughs. This has proven to be very successful giving peace of mind that water is available for cattle at the specified locations. We have had no issues with the flexiblity, reliability of the Water Rat. It is also helpful that we are linked in via Agriwebb.

malcolm

The "Water rat" is a simple unit that works well.
No installation. Easy to shift from one trough to the next.
Our unit stopped working, & Farmo promptly replaced it with a new unit, no hassles.

Michelle

Great tank monitoring system

Mitchell

Having a level meter on our water tank has meant so much to us in the last 12 months. There’s a huge sense of security in being able to detect unusual level changes, both monitoring the activity of our solar pump and also, during the dry season, the demand on our storage tank. Definitely a really worthwhile investment. Thoroughly recommend this little device.

James

Farmo has been great to deal with—excellent customer service and a team that genuinely cares. Their technology is simple to use and maintain, making it perfect for agriculture. Reliable, well-designed products and great support. Highly recommend!

Bryce

We had issues connecting with the WaterRat when we activated it but, working with customer service they quickly resolved the problem. The WaterRat was a cow life saver!! Our landowner, for some reason, shut the water off while we were away. The WaterRat alerted us when the tank was low and the device tipped on its side, with a stretch of 30+ weather it was worth its weight in gold!! Customer service is amazing!! I will be ordering more for all our pastures.

Dux

We use Farmo water rats in our troughs to keep an eye on the water levels . We can easily move them , as simple as taking them out and throwing them in the next trough as the cattle move paddocks . We can set alerts on our phones to let us know if a trough is empty . With tests they send the alert text within 10 seconds of tilting . They are very easy and cost effective.

FAQs

Yes. The Farmo Electric Fence Sensor is universally compatible. It works with any type or brand of electric fence. Simply clip the leads onto your hot wire and ground wire, and you're ready to go. No special energiser or wiring is required.

Yes, as long as there’s mobile network coverage (Telstra by default) the device will work. Data is sent over the specialised long distance CatM1/Nb-IoT part of the 4G and 5G networks, so you will find coverage goes further than voice calls on handsets.

No, the sensor doesn’t pinpoint the distance or direction of the fault. Based on the many experiences and testimonies shared by our customers, simply being alerted of a faulty fence line has saved them significant time and hassle.

The lithium battery will last for over a year before needing replacement. Keep the unit positioned out of reach of livestock, and ensure the lead clamps stay firmly attached to the fence wires to maintain reliable readings.
