Neuron Humidity IP21

Efficient humidity and temperature sensor for indoor IoT

The Neuron Humidity IP21 is a wireless IoT sensor from El‑Watch that measures relative humidity and ambient temperature. It’s built for indoor environments and can be mounted easily using cable ties or double-sided tape.

The sensor samples temperature every 30 seconds and typically reports every 2 minutes. If the humidity changes by more than 5 % RH since the last reading, it triggers an immediate transmission to alert for critical changes. The device is powered by a long-life battery with up to 10 years of lifespan, ensuring minimal maintenance.

You can adjust measurement settings such as frequency and alarm thresholds via the Neuron app, and receive notifications via push, email, or SMS when conditions go beyond defined limits. Commissioning is quick and reliable via a QR code on the sensor that registers it in the Neuron system.

Typical use cases include HVAC systems, transformer substations, industrial premises, storage facilities, and greenhouses — anywhere where both humidity and temperature matter to operations, quality, or energy efficiency.
