Wiring
The SNAP-AIRTD and SNAP-AIRTD-10 modules are
designed for three-wire connections, shown in the
diagram below.
If you use a four-wire connection (shown at the bottom
right), DO NOT connect the fourth wire, as it will cause
errors in the readings.
Two-wire connections (bottom left) are not
recommended, as they will degrade accuracy and
stability.
