Note:
In order to ensure the best detection and LoRaWAN® communication effect, it is recommended to install AM300 series as follows:

• There should not be any isolates or barriers in PIR and light detection range.
• Do not mount the device where the temperature is below/above operating range and temperature varies greatly.
• Stay far away from any heat source or cold source like oven, refrigerator.
• Do not mount the device close to where airflow varies greatly like windows, vent, fan and air conditioner.
• Do not mount the device upside down.
• Do not place the device right to the window or door. If you have to, you’d better pull the curtain.
