Selection guidance: choose the right probe for your Sonoff TH setup

Start by confirming the Sonoff controller model and the connector type. Many Sonoff TH devices accept RJ9 probes, but sensor wiring (two vs three-wire), cable length and intended mounting (air, surface, immersion) affect the correct SKU. When in doubt, compare the probe's compatibility notes on the product page and cross-reference with the Sonoff device manual.

Specification callouts and compatibility tips

• Connector pinout: RJ9 pins must match the controller’s expected signals - mismatched wiring can lead to incorrect readings.
• Cable length: keep cable runs as short as practical to minimise noise; if you need longer runs, consider shielded cable or sensor placement close to the controller.
• Environment: ambient probes are fine for room temperature - for liquids or harsh environments, choose a probe rated for immersion and appropriate sealing.

Accessory bundles and complementary products

Common bundles include the Sonoff TH controller plus an RJ9 probe, power supply options, and enclosure or DIN-rail mounting hardware. When creating a project BOM, consider adding a stable 12V 1A power supply if your Sonoff model requires external power and a small terminal block or breakout if you need to adapt RJ9 to other connectors.

Practical examples and compatibility checklist

Example: a university lab in Cape Town needs 10 probes with 2 m cable for classroom Sonoff TH kits. Confirm the probe cable length, place a stock reservation or request a quote to check availability and lead time in ZAR, and arrange branch collection to avoid courier delays. Estimated local lead times vary; stock items at Communica often allow same-week collection depending on branch availability.
