Chione Frost Alert Control Unit
- Manufacturer: Nesa
- Category: Meteorology – Climatology, SENSORS, Several
The NESA Chione unit is a monitoring device for detecting microclimatic conditions that can lead to late frosts in crops, whether from radiation or advection. The most important parameter to monitor is the wet-bulb temperature, the air temperature resulting from evaporative cooling under and within the foliage. Data is available in the cloud via a web interface or a mobile app.
Dry-bulb temperature -40°C to +60°C and wet-bulb temperature -20°C to +50°C, both with an accuracy of ±0.3°C and a resolution of 0.05°C; humidity 0 to 100% RH, ±2%, 0.2%. SigFox coverage up to 15 km and LoRa/NESA up to 8 km, GSM/GPRS depending on operator availability in the area. Die-cast aluminum housing, IP65 rated, -40 to +60°C.

Technical Frequently Asked Questions
What is Chione?
A control unit for frost alert in plants: detects microclimatic conditions that can lead to late frosts in crops, by radiation or by advection.
What does it measure?
Dry bulb temperature (-40°C ÷ +60°C), wet bulb temperature (-20°C ÷ +50°C) and humidity (0 ÷ 100 %RH), with two temperature sensors of each type.
What coverage and protocols does it have?
SigFox up to 15km, LoRa/NESA up to 8km, GSM/GPRS depending on operator availability in the area. Protocols: SigFox, LoRa/LoRa-WAN, proprietary, TCP/IP socket, MQTT.
How often does it transmit data?
The standard rate is 15 minutes; at temperatures below 5°C, it drops to 5 minutes. The data is available in the cloud via a web interface or app.
How does it feed?
With 1 x 3.3V 8000mA non-rechargeable C2 type lithium battery, or with rechargeable battery (2000mA) from power bank, mains or external mini solar panel.
How do I order it?
Depending on the radio module (CHIONE.SigFox, CHIONE.LoRa, CHIONE.NESA or CHIONE.SMS) and the power supply (N, 8000mA C2 type lithium battery; R, 2000mA rechargeable battery; P, 5W panel). Manufacturer's example: CHIONE.SMS · P.
