The transmitter wakes briefly, polls the SDI-12 probe, sends the VWC, EC, and substrate-temperature payload to the base station, and goes back to sleep. Aranet PRO 12, PRO 50, PRO 100, and PRO Plus base stations all accept the node. Pick the version that matches your row count and IP rating. Field swaps stay simple: pull the probe cable from the head, drop in the replacement transmitter, re-pair through the SensorHUB web server.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eSDI-12 input for substrate sensors:\u003c\/strong\u003e Plug a TerraLINK, Acclima TDR-310\/315, or Meter TEROS-12 head and start streaming VWC, EC, and substrate temperature.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e920 MHz Aranet LPWAN:\u003c\/strong\u003e Proprietary LoRa-based protocol with XXTEA encryption — 3 km line-of-sight, hundreds of feet through greenhouse structure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-year AA battery life:\u003c\/strong\u003e One 1.5 V lithium AA (Energizer L91) on a standard reporting interval — no panel wiring, no PoE.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePairs with Aranet PRO 12 \/ 50 \/ 100 \/ PRO Plus:\u003c\/strong\u003e Capacity scales with the base station;
