WIFI Data Logger (Inbuilt Sensor)

Model ML-4W

---

• Readings reach your dashboard over WiFi — software runs on the cloud or your own local server, so nobody has to walk to the device to collect data.
• Temperature and humidity in one unit — −20 to 60°C at ±0.5°C and 0–100% RH at ±3% RH, both to 0.1 resolution.
• Battery backup behind the 5VDC adapter — a 3.6V lithium half-AA keeps logging through a power cut, so the record has no gaps.
• 20K readings per channel on board — intervals from 1 second to 24 hours, buffered locally if the network drops.
