temperature humidity data logger wireless

Kingmach's wireless temperature and humidity data loggers run on a radio frequency like 433 MHz or 2.4 GHz, depending on the region and required range. In open air, line-of-sight transmission often reaches several hundred meters. Indoors, walls and machinery reduce that, but multiple loggers can form a mesh or star network to cover larger buildings. The sensor element typically uses a semiconductor-based humidity chip alongside a platinum resistance thermometer, giving a stability that holds up across thousands of cycles. Users may see typical accuracy around ±0.5 °C for temperature and ±3 %RH for humidity, though actual numbers depend on the calibration range ordered. Battery life varies with logging interval: a logger recording every 10 minutes might last over a year on a single lithium cell; more frequent sampling cuts that shorter. Loggers usually store data locally as a backup, holding tens of thousands of records. Access to data depends on the gateway configuration—some sites keep a local PC-based receiver, others push to a cloud server for browser access. Because Kingmach manufactures at scale for monitoring projects, many non-standard requests are possible: longer cables, alternative power supplies, custom alarm thresholds, or integration with third-party systems via Modbus or analog outputs. Their technical team often works with engineering firms on such specifications. For global shipments, the devices come with calibration certificates traceable to national standards if requested, and after-sales support is handled via regional distributors or direct communication with the factory.
