WIRELESS 4-20MA CURRENT LOOP SENSOR / BRIDGE
Overview
The 4-20mA sensor uses a 10-bit ADC to measure an analog value between 4 and 20mA with a 10uA resolution. If the measured value rises above or falls below the configured thresholds, an alert is sent over the wireless network. The Armored Sensor™ IP67 weather-proof enclosure makes the sensor suitable for outdoor and industrial use.
The 4-20mA sensor can also be used as a bridge device to enable a wide variety of sensors with only a 4-20mA output. See the article Using Radio Bridge’s 4-20mA Current Loop Sensor to Connect Off-the-Shelf Devices to LoRaWAN for more information.

WIRELESS IP67 VOLTAGE SENSOR
Overview
The wireless voltage sensor measures voltages between 0-30V with 10mV precision. When the voltage rises above or drops below a threshold, an alert is sent over the wireless network. An indoor/smart building version is also available for low-cost applications.
