Efento 4-20 mA Sensor Interface

The Efento 4-20 mA Sensor Interface provides seamless connectivity for analog sensors to the cloud, offering a versatile and reliable monitoring solution. This device is equipped with up to 2 analog interfaces (2 x 4-20 mA), allowing simultaneous operation with two external sensors.

Key Features

Cloud Integration

• Data from connected analog sensors can be displayed as current (4-20 mA) or converted to other measurement types via the Efento Cloud platform.
• Build a remote monitoring system by adding the Efento Gateway and Efento Cloud.

Flexible Configuration

• Use the free mobile application to configure the device, set measurement intervals, read data from memory, generate reports, and define alarm thresholds.
• Measurement intervals are user-configurable, ranging from 1 minute to 10 days.
• User-friendly alarm thresholds send immediate alerts to the platform if preset limits are exceeded.

Reliable Data Storage

• Storage capacity of up to 40,000 measurements in internal memory.
• When the memory is full, the oldest data is automatically overwritten.

Power Options

• Operates on a replaceable battery set of 3 x AA (6300 mAh) with up to 5 years of maintenance-free operation.
• Alternatively, powered via a 5V USB connection with a rechargeable 1000 mAh battery.
