The SF-421-SS has an SDI-12 digital output. The detector is a combination of two temperature sensors (precision thermistors) in a single housing. One sensor is designed to mimic a plant leaf the other a flower bud.
The SF-421-SS provides close approximations to leaf and bud temperatures and has a temperature measurement range of -50 to 70°C. Typical applications include leaf and bud temperature estimates in cropped fields, orchards, and vineyards. Leaf and bud temperatures returned by the detector can then be used to alert growers to the potential of frost damage to crops. Sensor includes IP68 marine-grade stainless-steel cable connector 30 cm from head to simplify sensor removal and replacement for maintenance and recalibration.
Utilising the SF-421 Sensor in a custom IoT (Internet of Things)
The SNiP-LBT is a ‘Sensor Node Integrated Package’ for LoRaWAN or CATM-1 communication of real-time leaf and bud temperature measurements, for continuous plant, light and environmental monitoring.
The base SNiP-LBT integrates 1x SF-421 Sensor and 1x S-NODE to a site’s unique network, communication and power requirements.
