Temperature & humidity sensor Milesight AM307-915M

The Milesight AM307-915M is a freestanding temperature and humidity sensor designed for indoor and outdoor climate monitoring. Its compact footprint (100.8 mm width, 114 mm depth, 22 mm height) allows unobtrusive placement on shelves, desks, or mounted in sheltered outdoor locations. The device is intended to provide long-term environmental data with minimal maintenance, featuring a high-capacity 2700 mAh battery that supports up to six years of operation under typical conditions. Built to meet RoHS standards, the sensor offers a reliable and environmentally conscious option for tracking temperature and relative humidity in homes, offices, storage areas, and semi-exposed exterior spaces.

Advantages

The sensor combines extended battery life with a compact design to reduce the need for frequent servicing and to simplify installation in confined spaces. Its freestanding form factor allows flexible positioning without dedicated fixtures, and the device provides stable temperature and humidity readings suitable for routine monitoring. Compliance with RoHS standards ensures that the materials used meet environmental and safety requirements.

Suitable for

• Residential climate monitoring (living rooms, bedrooms, basements)
• Office environment control and HVAC verification
• Storage and archive monitoring where temperature and humidity stability matter
• Semi-outdoor or sheltered outdoor locations such as covered terraces or porches

Key specifications

• Form factor: freestanding
• Battery capacity: 2700 mAh
• Estimated battery life: up to 6 years (typical conditions)
• Physical dimensions: 100.8 mm (width) × 114 mm (depth) × 22 mm (height)
• Measured values: temperature and relative humidity
• Environmental compliance: RoHS compliant

How to use

Place the Milesight AM307-915M on a flat, stable surface or in a sheltered outdoor location away from direct sunlight, rain, or heat sources to ensure accurate measurements. For indoor use, position the sensor at typical human-occupied height and away from vents or windows that may cause transient readings. If monitoring a storage area or archive, locate the device near the items to be protected but clear of obstructions that limit air circulation. Regularly check the device status through the connected monitoring system according to your Milesight integration method.

Recommendations

To maximize measurement accuracy and battery life, avoid exposing the sensor to extreme temperatures outside its operating range, keep it out of direct sunlight, and ensure it is installed where air can circulate freely around the sensing elements. Schedule periodic checks in line with your facility management routine to confirm readings and battery status.
