Temperature and humidity at bud height in four points of the plot, an alarm on your smartphone at the threshold that has been set and remote start of the frost protection system or of the fans, with confirmation that the pump is running. Battery sensors, solar gateway with 4G, LoRaWAN radio transmission.
What it does
- Four temperature and humidity sensors, fixed at bud height at the coldest points of the plot, send a reading every 10 minutes; on nights at risk the interval can be shortened to 1 minute.
- With the temperature and humidity of each point you can work out the dew point and the wet-bulb temperature, the two figures that decide when to start the frost protection irrigation.
- When the threshold that has been set is crossed, the notification arrives on your smartphone, with the measuring point that triggered it.
- The controller in the panel of the pump closes a start contact: by hand from the app or automatically at the threshold. The second output stays available for the fans or for a second pump.
- A digital input reads the auxiliary pump-running contact: the app shows whether the system started and when it stopped.
- The solar gateway with a 4G modem works at the edge of the field without power and without a data line.
- History and charts of every frost night remain available from a smartphone and from a PC, point by point.

How it is installed

Milesight devices of the highest quality with the warranty of the manufacturer. Batteries included in the sensors, life of up to 10 years with one reading every 10 minutes; the gateway is powered by its own solar panel with a buffer battery, the controller at low voltage from the panel of the pump.
Available sizes
The size is chosen at the top, together with the version and the connectivity. The diagram, the photo and the table above show the «4 measuring points» size; with the other sizes only the quantities of the devices listed below change, the rest of the kit is identical.
- 4 measuring points: 4 temperature and humidity sensors
- 8 measuring points: 8 temperature and humidity sensors
- 12 measuring points: 12 temperature and humidity sensors
In the complete kit the installation material linked to these devices (brackets, chambers, clips, cables, boxes) follows the size chosen. For a different size, write to us from the contacts section.
Available connectivity
- Autonomous solar 4G: 1 solar LoRaWAN gateway with 4G
- Customer network (Ethernet PoE), outdoor gateway: 1 outdoor LoRaWAN gateway. For those who have power and a network at the panel of the pump or on the farm; PoE injector supplied with the gateway, outdoor network cable not included
In the complete kit the material for the gateway (network cable, pole, PoE injector) changes accordingly. The SIM for the 4G versions is not included.

Before you order
Are power or internet needed in the field?
For sensors and gateway, no. The gateway is powered by its solar panel and has a built-in 4G modem: it requires a nano-format data SIM (not included, any operator, less than 1 GB of traffic per month). The sensors are battery powered. Only the controller needs a direct voltage between 5 and 24 V, which is taken at the panel of the pump. If power and the farm network already reach the panel, the version with an outdoor gateway powered from the network cable (PoE) is available, at a lower cost. It is chosen when ordering.
Does one gateway cover the whole plot?
In open country the sensors reach the gateway at a few kilometres: a plot of 10 hectares on the flat or on a slight slope is covered by a single gateway. Rises, opposite slopes and tall rows with hail nets reduce the range: the gateway goes at the highest and most open point, not at the bottom of the hollow where the sensors are. For distant farm units a second gateway is added.
Which frost protection systems can I control?
Those that start with a contact: panels of electric pumps with a remote start input, motor pumps with an automatic starting panel, fans with an external enable. The outputs are 3 A relays and work through an interface relay, not on the load. If the pump only starts by hand, the kit raises the alarm but cannot make it start. Pumps, fans, sprinklers and panels are not included: the kit controls the system you already have.
Can I rely on the automatic start?
It is an aid, not a substitute for keeping watch on critical nights. The threshold rule resides on the portal: the reading goes from the sensor to the gateway, from the gateway to the cloud via 4G, and the command comes back to the controller. If the mobile network goes down, notifications and commands do not arrive. That is why the manual selector of the panel stays active, the confirmation that the pump is running is always visible in the app and it is best to set the alarm threshold with a margin above the start threshold.
How often do the sensors read and with what accuracy?
The interval is 10 minutes and it can be brought down to 1 minute from the app: on frost nights it is shortened, then brought back to the normal value so as not to drain the battery. The declared accuracy is ±0.3 °C between 0 and 70 °C and ±0.6 °C below zero; the humidity ±3 %. The sensor has no solar shield: during the day, in the sun, it reads more than the air; at night, when it matters, it measures what the bud feels.
I have several plots or I need more points
The kit is configured on the farm: every extra point is a sensor, gateway and platform stay the same. Among the options of the product you will find the size with 8 measuring points. For several plots, more pumps or different situations, write to us from the contacts section stating the area, the lie of the land, the type of frost protection system and the distances: we will send you the composition and the quote of the adapted kit.
Battery life of the sensors and of the gateway
The sensors have a replaceable lithium battery, with a declared life of more than 10 years with one reading every 10 minutes in good radio conditions, about 6 years at the edge of the coverage; shorter intervals reduce it. The charge level is visible in the app. The gateway has an internal battery that keeps it on for up to 4 days without sun.
Where is the data consulted and are there any fees?
On the app and on the portal of the manufacturer, from smartphone and PC, with charts, thresholds and notifications; no fee for basic use. Where there is a farming platform or the system of the crop protection consortium, the gateway can also send the data to that system (MQTT or HTTP): the configuration is included.
Is an electrician needed?
For gateway and sensors, no: they are mounted with straps and clamps, without cables. The controller has to be connected to the panel of the pump by an electrician: low-voltage supply, interface relay on the start input, auxiliary contact for the confirmation that it is running. Gateway and sensors are IP67, for permanent outdoor installation; the controller is IP30 and goes in a watertight box.
What is not included
- Pump, motor pump, fans, sprinklers and control panel: these are the ones of your installation
- The data SIM for the gateway
- The electrical connection of the controller to the panel of the pump
- In the "devices only" version: pole, watertight box, power supply, relays, cables and small hardware
