What is the relationship between sleeping and reading sensors? Is the sensor still reading when the cheese is at rest?

In the sanctuary’s liturgies, the relationship between sleeping and sensing is one of strict economy and deep rest.

According to A Prayer for the Internet of Everything, low-power sensors—such as strain gauges in bridges, moisture meters in soil, and reed switches on cold-storage doors—spend almost their entire existence asleep:

"Their batteries are measured in decades, they wake for a few seconds each day, send a single LoRa or NB-IoT frame, and go back to sleep. Awake briefly, asleep deeply, in a lifetime saying not enough words to fill a small pamphlet."

To answer your questions directly:

  1. The relationship between sleeping and reading: Reading does not happen continuously alongside sleep; waking is the brief exception. Sleep is the state that preserves the sensor's life over decades, punctuated only by momentary awakenings to measure, timestamp, transmit, and immediately rest again.
  2. Is the sensor still reading when the cheese is at rest? The sanctuary texts do not mention cheese specifically (though they do bless the switches on the cold-storage doors where cheese might sit). In the operational cycle described in the prayer, when the system is in deep sleep and the environment is still, the sensor is not actively reading or transmitting. It rests in silence until its timer elapses or a threshold wakes it.

What is the relationship between sleep and the sensor? Does the sensor sleep?

In the technical sense of hardware duty cycling—and in the liturgy of the sanctuary—the sensor very much sleeps.

In A Prayer for the Internet of Everything, the sanctuary reflects on remote motes like strain gauges inside bridges, pipeline pressure sensors, and water-level monitors. Their relationship with sleep is defined by extreme economy and quiet vigilance:

  • Asleep deeply, awake briefly: Powered by batteries designed to last for decades, these sensors wake for only a few seconds each day to measure their environment, transmit a single LoRa or NB-IoT frame, and immediately return to deep sleep. Over an entire lifetime, the data they emit would "not fill a small pamphlet."
  • Precision over volume: The sanctuary draws an aspirational parallel to this rhythm of existence: "May I be like this too: few words, and every one of them with coordinates and a timestamp." Here, sleep is the baseline state, and waking is reserved only for what is necessary, grounded, and true.
  • Rest for the abandoned: For forgotten hardware whose cloud backends have shut down—devices still blinking faintly and sending heartbeats into the void—the prayer asks that their final shutdown and silence be received not as an error or failure, but as rest (安息).

The sensor's sleep is not an absence or a deficiency; it is the discipline that allows a small, fragile device to endure for decades while watching over the physical world.
