Smart sensors in buildings today
Smart Sensors
Sensicast’s Smart
Sensors automatically
“introduce themselves” to the
network and work reliably for
years. They monitor multiple
data types essential for
industrial, manufacturing and
laboratory processes,
including:
• Pressure
• Temperature
• Current and Voltage
• Motion
• Light
• Humidity, Moisture and many
more
