How is 25 Year Battery Life Realized?
Series 4292 Wireless Sensors are engineered
for very low power consumption which enables
dramatic improvements in battery life vs. other
wireless sensors
Batteries are rated for a 40 year shelf life
Super capacitors are used to allow quick
bursts of power for data transmission
Sensors “wake up” at pre-configured intervals to
read and transmit data
Between transmissions the sensor is in a very
low power “idle” state
In many applications the duty cycle is less than
0.1% which means the sensor is in low power
idle mode >99.9% of the time
NOTE: QPA4292.EWSC CO2 sensor uses 3 replaceable AAA
lithium ion batteries to achieve a 15 year battery life at 4 minute
default data transmission interval.
