Wireless Environmental Sensor Node

A low-power node that samples environmental conditions and reports them over a wireless link. Wireless Environmental Sensor Node combines 6 component groups into a buildable stage you can source from a single catalog. It is a common building block in building automation.

How the assembly works

Each block in Wireless Environmental Sensor Node maps to a catalog component family, so the design can be quoted and sourced as one package. The bill of materials below lists the role each part plays and a representative specification.

Selecting parts

Start from the headline parameters, then size each block: the regulator or controller sets the operating point, passives are chosen for ripple and stability, and protection is rated above worst-case stress. Use the linked categories to compare options.

Sourcing the build

Because every block is a stocked catalog family, the whole assembly can be quoted together with consolidated lead times. Request a quote with your target volume and we will return availability across all blocks.

Build sequence

  1. Verify the supply rail and reference ground at the board edge first.
  2. Place and verify the microcontroller (Low-power MCU with ADC and I2C).
  3. Place and verify the sensor element (Temperature / humidity / pressure, I2C).
  4. Place and verify the wireless module (2.4 GHz or sub-GHz radio module).
  5. Place and verify the ldo regulator (3.3 V low-quiescent LDO).
  6. Place and verify the decoupling network (100 nF + bulk per rail).
  7. Place and verify the status indicator (Indicator LED with series resistor).
  8. Energize gradually, measure against the parameter table, and qualify at rated load.

Frequently asked questions

How many parts are in Wireless Environmental Sensor Node?
The reference design is organized into 6 functional blocks; the bill of materials expands each block into the specific component family and quantity.
Are the listed specifications final?
They are representative starting values from standard reference-design practice. Confirm each against your load, environment, and the manufacturer datasheets before release.
Do you provide a quote for the full bill of materials?
Send your target volume and we will return availability and volume pricing across every block in the assembly.
Can I source the whole Wireless Environmental Sensor Node from one supplier?
Yes. Every block maps to a stocked catalog category, so the assembly can be quoted and shipped as a single consolidated order.
