Using artificial intelligence (AI) to detect pest activity

A sensor node comprising:

• one or more sensors comprising a thermometer, a hygrometer, a microphone, and an ohmmeter;
• a communication interface;
• two metal fasteners to mount the sensor node to a wood item;
• one or more processors;
• and
• one or more non-transitory computer readable media storing instructions executable by the one or more processors to perform operations comprising:
• measuring, by the thermometer, an ambient temperature;
• measuring, by the hygrometer, an ambient humidity;
• measuring, by the ohmmeter, a resistance of the wood item between the two metal fasteners;
• determining, based on the resistance, a moisture content of the wood item;
• based at least in part on determining that:
• the ambient temperature is greater than a temperature threshold,
• the ambient humidity is greater than a humidity threshold, and
• the moisture content is greater than a moisture threshold, capturing audio data by the microphone, the microphone coupled to the wood item;
• and
• based at least in part on determining that the audio data indicates pest activity, sending, by the communication interface of the sensor node, a notification of pest activity, the notification including the audio data.
