Enhance health and safety of people in warehouses and other facilities where high humidity can make it difficult for workers to keep cool in elevated temperatures, potentially leading to heat exhaustion The temperature measuring range of -40°C to +85°C with a resolution of 0.1°C and accuracy of ±0.6°C from -40°C to 0°C, ±0.4°C from 0°C to +60°C, and ±1.2°C from +60°C to +85°C. The humidity sensor can measure from 0% to 100% RH with an accuracy of ±2% at +25°C, ±3% from 0°C to +70°C and 10% to 90% RH, and ±7% from 0°C to +70°C and 0% to 10% or 90% to 100% RH. When the unit is turned on, it operates in fast sample mode and sends data every two seconds. After five minutes, the node enters the default mode and sends data at five-minute intervals. Sample rates of 15 minutes or 64 seconds are user-selectable. Models with 900 MHz radios transmit at 1 W (30 dBm) or 250 mW (24 dB user-selectable). The 250 mW mode reduces the range but improves battery life in short- range applications. For 2.4 GHz models, transmit power is fixed at about 65 mW (18 dBm). When operating in storage mode, the radio is shut off to conserve battery life.
Conclusion Effective EHM systems in Industry 4.0 factories monitor vibration and temperature to help ensure high levels of uptime. Humidity and temperature sensors can also improve operational performance of data centers and preserve goods like vaccines or fresh produce in warehouse and logistics operations. These systems can use wired or wireless connectivity to monitor multiple parameters.
