What is Air Sentry Neo?

Battery-powered multi-sensor node tracking temp, humidity, CO2, VOCs, NOx—low-power via nRF52810, under 500µA sleep, for workshops spotting thermostat lies and fume risks.

How to design a low-power multi-sensor node?

Prioritize PMIC for regs, pick nRF over ESP32 for battery, iterate fast on power glitches, use Zephyr for control—no daughterboards, integrate tight.

Will nRF52 beat ESP32 for IoT battery life?

Yes, granular modes crush ESP's idle draw—but expect clock/BLE debug hell first. Week-plus runtime real if you nail it.
