Pollux releases third product with Epishine’s light cell
Pollux (Swartsjö, Sweden), one of Epishine’s (Linköping, Sweden) first customers, which already has two light-powered products on the market, is now revealing a new product in the Hadar family: “Hadar Cold”, a connected sensor for sub-zero temperatures. The sensor is designed to help preserve, extend, and ensure the shelf life of refrigerated products, without the maintenance cost for replacing batteries.
"When your business model relies on fresh, delicious, and safe-to-eat food, optimising your entire cold chain to keep things at the right temperature should be your top priority. Today businesses often replace batteries at a predetermined interval, which can result in them replacing a battery that still has 30-40% energy left. Furthermore, batteries and cold climate isn’t a good match which means that a standard battery can lose as much as 50% of its capacity in temperatures sub -10°C. For Hadar Cold this is not an issue as it runs completely without batteries,” says Lars Mokvist from Pollux.
“Our solar cells are optimised to generate sufficient electricity from ambient light, such as LEDs and fluorescent light to power low energy devices. It can harvest the tiniest amount of energy and an integrated energy store allows the devices to operate for several days in total darkness. Removing the maintenance cost of battery replacement strengthens our customers’ business cases, and the reduced usage of disposable batteries benefits our environment,” says Mattias Josephson, VP business development, Epishine.
The Hadar family consists of wireless, battery free and maintenance free temperature and humidity sensors. Hadar and Hadar Home are designed for smart buildings and smart homes (Hadar Home is designed to work in situations with very little light to harvest). Hadar Cold is designed and optimised for temperatures below zero (-20°C to +60°C) targeting retail.
