{"product_id":"lwl04-lorawan-water-leak-sensor","title":"LWL04: LoRaWAN Water Leak Sensor","description":"\u003cp\u003eThe Dragino LWL04 is a LoRaWAN Water Leak Sensor. When there is water between the bottom 3 metal posts, the LWL04 indicates a water leak event and uplinks to your IoT server via the LoRaWAN network.\u003c\/p\u003e\n\u003cp\u003eThe Dragino LWL04 does not need to be fixed, only placed on the ground. The bottom three metal columns can be adjusted to change the height. Only when there is water between the three metal columns, will it cause a short circuit alarm.\u003c\/p\u003e\n\u003cp\u003eThe LWL04 can be activated from the bottom of the housing with a magnet, and the light will indicate when the magnet is close. Its main unit has a sealant ring, which achieves IP65 waterproof.\u003c\/p\u003e\n\u003cp\u003eThe LWL04 is powered by a CR123A non-rechargeable battery, targeted for long term use. These batteries can provide about 16,000 ~ 70,000 uplink packets, which results in 2 ~ 10 years battery life. After the battery runs out, users can easily open the enclosure and replace with new CR123A batteries.\u003c\/p\u003e\n\u003cp\u003eThe LWL04 will periodically send data every day as well as for each water leak event. It also counts the water leak times and calculates the last water leak duration. Users can also disable the uplink for each water leak event, instead the device can count each event and uplink periodically.\u003c\/p\u003e\n\u003cp\u003eEach LWL04 is pre-loaded with a set of unique keys for LoRaWAN registration. Once these keys are registered to a local LoRaWAN server,  the device will auto connect after it has been powered on.\u003c\/p\u003e","brand":"Dragino","offers":[{"title":"Default Title","offer_id":54380397199697,"sku":"LWL04-EU869","price":38.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1056\/2155\/3489\/files\/DRAGINO-LWL04_01.jpg?v=1782456640","url":"https:\/\/shop.ukiot.io\/products\/lwl04-lorawan-water-leak-sensor","provider":"UKIoT","version":"1.0","type":"link"}
