REAL USE CASE SOLUTION e Devonian Gardens is a three-acre exotic horticultural refuge on the top floor of e CORE Shopping Centre in Calgary, Alberta, Canada. e horticultural team at Devonian Gardens noticed some trees were exhibiting signs of light stress and other stressors. Devonian Gardens installed sensors built on Semtech's LoRa® devices throughout the gardens as part of a system to monitor various factors affecting plant health. Using the sensors to capture lighting data from different positions, specialists are able to quantify light spatially in the garden. A spatial representation provides insight for future species selection and placement, maintenance, and in future lifecycles of lighting for optimal plant health. Temperature, humidity and barometric pressure sensors measure conditions accurately and in real time, and characterize this data for the horticultural team to further help plants thrive. CONSISTENT DATA COMMUNICATION With LoRa-enabled photosynthetic active radiation (PAR) sensors readings from different positions throughout the gardens, specialists are able to leverage sensor data to quantify light spatially in the garden. A spatial representation helps in future species selection and placement, maintenance, lifecycle of lights for optimal plant health. STANDARDS-BASED RELIABILITY e LoRaWAN® networking protocol is designed to wirelessly connect sensors to the Cloud in regional, national or global networks. e specification provides seamless interoperability between devices in any deployment - anywhere. Many LoRa-based devices are LoRaWAN Certified CM by the LoRa Alliance®. Certification further ensures devices meet strenuous requirements on quality, security, reliability, and safe operation. INDOOR AGRICULTURE 6 "Now we have an opportunity to manage these precious gardens with science. We are understanding various light models and fitting them with the right species." Nan Xie IT Senior Engineer, the City of Calgary Semtech Corporation - LoRa Devices Real World Solutions - Smart Agriculture semtech.com/LoRa HOW IT WORKS Sensors measure conditions accurately and in real time, and characterize this data for the horticultural team to further help plants thrive. LOW POWER In addition to the superior range and reliability of data transmission, LoRa devices feature extensive power- saving features that make it possible for a wireless sensor to last up to 10 years on a single battery. As a result, costly maintenance and replacement costs are effectively reduced or eliminated.
