Editorial narrative

Sensor Hub Noise Sensing is a solution that is designed to respond to any solution where sound and/or noise level monitoring is needed. The RK300-06A Noise Sensor is a kind of digital and modular multi-function sound level meter. Using a digital signal processing chip and digital detection technology, it has high reliability, good stability, and wide dynamic range, without range switching. The sensor can be widely applied to various machines, vehicles, ships, and electrical appliances for smart homes, warehousing, and public places. Other industrial noise measurement use cases where environmental noise measurement is needed can also benefit, like labor protection, and industrial hygiene. The Splitter cable can connect several Sensor Probes and Probe IOs to a single Sensor Hub port. The distance between the Sensor Hub and Sensor Probe/Probe IO can be extended via the Extension cable. Note ： The Sensor Hub has two variants based on the communication type - LoRaWAN only and LoRaWAN+NB IoT. SensorHub's NB-IoT module supports two types of LTE (Long-Term Evolution) categories, namely CAT M1 and CAT NB2. CAT M1 offers higher data rates and lower latency, while CAT NB2 provides ultra-low power consumption and greater coverage, making it an ideal choice for devices that operate on batteries and require long-term connectivity. Sensor Hub with Sensor Probe IO and connected sensor cannot be powered on batteries. You need to use the included power supply only. Features Rigid and robust construction External DC power supply (optional) Solar panel power source (optional) LoRaWAN/NB-IoT communication Long service life High sensitivity Parameter Value Range 30 ~ 130 dB Accuracy ±3 dB @23 ℃ (±5 ℃) Frequency response 31.5 Hz ~ 8 kHz Microphone Capacitive microphone Power consumption <20 mW Response time <200 ms Operating temperature -10 ℃ ~ +50 ℃ @5-80% RH Shell material ABS & 304SS Included in the Package: 1x Sensor Hub 1x Sensor ProbeIO 1x RK300-06A Noise Sensor 1x Power
