Wireless vs Wired Building Sensors – The Real Cost Comparison

The True Cost Is in the Installation, Not the Sensor When comparing wireless and wired sensors for building monitoring, most calculations focus on device cost. The real difference is in installation. A wired temperature sensor may cost €30 – but the cable, tray, conduit, I/O module, electrician hours and commissioning bring the total to €300–500…

RSSI Signal Strength, Battery Life and cost

What Is RSSI and Why Does It Matter? RSSI stands for Received Signal Strength Indicator. It is measured in dBm (decibels relative to 1 milliwatt) and tells you how strongly a sensor’s radio signal is being received at the LoRaWAN gateway. The scale is negative — the closer to zero, the stronger the signal. RSSI…
