Analog

Generic analog sensor node — read anything 0–3.3 V, deep-sleep between samples.

The OGLAS analog node is the workhorse. It’s a battery-powered wireless device that wakes up, reads an analog input, sends the value, and goes back to sleep. Same firmware drives sensors for soil moisture, light, voltage, level — anything that comes out as a 0–3.3 V signal.

What it does

On each wake cycle:

  1. Reads an analog input (12-bit ADC, 0–3.3 V).
  2. Sends the reading to your hub.
  3. Waits for confirmation.
  4. If no confirmation, sleeps briefly and retries so the hub knows the reading is stale.
  5. Once confirmed (or after retry limit) deep-sleeps for the configured interval.

The reading counter and last value survive deep sleep so a power-cycle doesn’t lose history.

Hardware

Two hardware variants are available — pick whichever suits the install:

  • A readily-available variant with USB-C and integrated radio. Good all-rounder.
  • An ultra-low-power variant with lower idle current, better suited to long-term battery installs.

Both run from a single LiPo cell with deep-sleep current low enough for season-long deployments — see Off-grid power.

Configuration

Configurable reporting interval, node name, analog pin mapping, and reading key — set at build time to match your install.

Pairs well with

  • Tank level — for many tank installs the analog node is the tank level sensor (with a level transducer feeding the ADC).
  • LoRa Hub — picks up the readings and logs them.
