Do Farm Apps Connect to Farm Sensors and Equipment in the Philippines?

A sensor measures one thing in one spot, again and again: water depth, soil moisture, rain or heat. Then it logs the reading or sends it to your phone. That sounds like the future, but the decisions it serves are old ones. When do I irrigate? Is rain coming before I spray?

So the real question is not whether sensors are modern. It is whether a reading you cannot take by eye will change what you do, often enough to pay for the device and its upkeep.

Key points

• Farm sensors measure one thing in one place, like water depth, soil moisture or rainfall.
• The cheapest water sensor is a simple tube. A field water tube shows when a paddy needs water under alternate wetting and drying (AWD).
• Philippine projects exist: the AutoMonPH water level sensor, and the SARAI weather stations and soil moisture system.
• Sensors need batteries, signal and someone who acts on them. They pay best when a group shares them.
• anee.io does not connect to sensors or machines. It uses forecasts, satellite pictures and your notes.

What farm sensors exist, and what do they measure?

Most farm sensors fall into four groups. Each has a low tech cousin that many Filipino farmers already use.

What is the low tech version for rice water?

It is a field water tube for AWD, a water saving method. The tube sits in the paddy so you can see the water level even below the soil surface. Here is the rule.

That tube is a sensor you read yourself. Electronic water level sensors do the same job, but they send the reading by text so you need not walk out to every paddy.

Which Philippine farm sensor projects can you learn from?

AutoMonPH: water level by text message

AutoMonPH is an electronic device that measures paddy water level, based on AWD. It came from the WateRice project of PhilRice, IRRI, the National Irrigation Administration and the Bureau of Soils and Water Management. Farmers receive their field's water level and irrigation timing advice by SMS. Meanwhile, a central database tells the irrigators association which areas need water.

It started in 2016 with the Bantug Bakal Irrigators Association in the Science City of Munoz, Nueva Ecija. Later, PhilRice put two improved sensors on each member's farm, covering 252.85 hectares. The first battery lasted only four days, and a low battery gave wrong readings. The improved sensor reportedly runs more than 60 days.

SARAI: weather stations and soil moisture

Project SARAI of UPLB, funded by DOST PCAARRD, began in 2013. Its automatic weather station measures rainfall, humidity, wind speed and direction, soil temperature and soil moisture. As of August 2026, SARAI is rolling out nationwide through its regional hub program, SARAI CeNTRO.

SARAI also built WAISS, a water advisory system for irrigation scheduling. Its field unit has soil moisture sensors, a data logger that transmits, and a 5 volt solar panel. The logger sends readings to the software by text message.

When do farm sensors pay off for a small farm?

They pay off when a decision depends on a reading you cannot easily take by eye, and when someone acts on it every time. Sharing the cost helps. AutoMonPH served a whole irrigators association, not one paddy. So did the central database that told the system manager which areas needed water.

• Worth a look: a group sharing one irrigation system, high value crops under irrigation where water timing decides the harvest, or a farm you run from far away.
• Probably not yet: one or two paddies within walking distance, where a tube, a rain gauge and a daily walk give the same answer.
• Plan the upkeep: batteries or solar panels, phone signal for the texts, cleaning after floods, and protection from theft.

Treat sensors as one group of crop production tools, and rarely the first one to buy. Our guides to precision agriculture and monitoring crop health without a drone cover the cheaper tools that come first.

Which farm apps work with farm sensors and equipment?

Some farm platforms, mostly built for large farms abroad, link to weather stations, soil probes or machine data. Before you buy a device or an app, check the maker's own list of devices it supports. Both must speak to each other, and many do not.

The Philippine projects above do not need a separate farm app. AutoMonPH and WAISS send their own advice by text message, which works on any phone.

How does anee.io work without sensors?

anee.io does not connect to sensors, weather stations, tractors or drones. Instead, it works from data any farmer can get, plus what you see in the field.

First, the farm weather forecast shows rain and heat for each lot's location beside your plan, with a reminder when rain falls on a spray day. Next, Satellite Weather plays back clouds and rain radar and tracks every typhoon near your farm.

For crop health, Satellite Analysis reads Sentinel 2 pictures and Sentinel 1 radar of a field you draw. Anee, the smart farm technician inside anee.io, then names the weak spots to walk first. That uses credits. Our guide to satellite images of your farm explains what those pictures can and cannot show.

Your own readings count too. Write your AWD tube depth or rain gauge reading as a note on the day, even offline. Over a season, those notes become the record a sensor would have kept.
