Description
The Milesight AM103/AM103L (model code: MS-AM103 / MS-AM103L) is a LoRaWAN air quality sensor that adds CO2 monitoring to temperature and humidity tracking, giving Saudi facility managers a fuller picture of indoor comfort and ventilation performance. It is designed for meeting rooms, classrooms, and offices where CO2 build-up signals poor ventilation.
- Connectivity: LoRaWAN (CN470/EU868/US915/AS923 and more)
- CO2 (NDIR): 400-5000 ppm, accuracy +/-(30ppm + 3% of reading)
- Temperature: -20C to 60C, accuracy Typ. +/-0.3C
- Humidity: 0-100% RH, accuracy Typ. +/-2% RH
- Power: 2 x replaceable ER14505 batteries, up to 5 years life (AM103L)
- Optional 2.13-inch e-ink display (AM103 model)
The AM103/AM103L configures over NFC using the Milesight mobile app, so installers can commission units without opening a gateway session on site. Onboard storage holds up to 640 readings for retrieval if connectivity drops, and Smart Screen and Hibernation modes extend battery life further.
It measures 68 x 65 x 20.5mm, weighs 182.5g, and carries an IP30 rating suited to standard indoor enclosures, offices, classrooms, and meeting rooms rather than outdoor or washdown environments. On AM103 units, the e-ink display shows a traffic-light color code (green, yellow, red) with emoticon feedback, giving occupants an at-a-glance air-quality read without needing a dashboard. AM103L drops the screen for a lower-profile install where only backend monitoring is needed.
Both variants run on dual 2700mAh ER14505 Li-SOCl2 batteries, rated for roughly 3 to 4.5 years on the AM103 and 3.3 to 5 years on the AM103L depending on the reporting interval selected, and the batteries are field-replaceable rather than requiring the whole unit to be swapped out.
For Saudi facility teams managing multiple sites, the combination of long battery life, NFC commissioning, and multi-band LoRaWAN support means one sensor SKU covers office towers, schools, and government buildings without re-specifying hardware per site.
