Hunter WR‑CLIK
$58 under your budget
800 ft of transmit range, the longest here and roughly 2.6x the Rain Bird's ~300 ft, with the same first-drop Quick Response trigger and a 37°F freeze cutoff — so no wire is fished from the eave to the garage.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
The battery is sealed in. Hunter rates it around 10 years, but it is not user-replaceable — at end of life you buy another $92 sensor, not a $5 cell. And treat the range claim as marketing: 800 ft is line-of-sight, while brick, stucco, foil-faced insulation and metal roofing routinely cut effective range below 100 ft, which is why installers mount the receiver within 100 ft no matter what the box says.

■ Every product has a catch. Verdicts that hide it are how bad buys happen.
Don't buy this if…
- you want a Wi-Fi smart irrigation controller (Rachio, B-hyve, Hydrawise) that uses local weather forecasts to skip watering — these often replace, rather than pair with, a physical rain sensorSmart sprinkler controller verdict →
- you have a non-irrigation rain sensor need (e.g. closing skylights, automotive wipers, or weather station rainfall logging)
- you have a soaker-hose / drip system on a battery hose timer with no sensor input terminals
- you specifically need a soil-moisture sensor (root-zone-based shutoff) rather than a rainfall sensorSoil moisture sensor verdict →
Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the Hunter WR-CLIK is right for you
It avoids every trap below — and for family of 4, under $150, it is the pick because it delivers:
Your controller may have nowhere to plug it in
A universal rain sensor is a switch spliced into a 24 VAC controller's normally-closed sensor terminals, or into its common wire. Battery hose timers and proprietary smart hubs — Rachio Smart Hose Timer, B-hyve faucet timers — have no sensor input at all, so no sensor on this page will work with them. Open the controller and find the SEN or COM pair before you buy anything.
One Amazon listing, two different sensors
Orbit sells a hard-wired child ASIN and a wireless child ASIN under one near-identical title at very different prices — the wireless kit is B0FWNPB76N at $73.02, the wired 57069N is $13.71. Hunter is the same shape of trap the other way: WR-CLIK, WRF-CLIK and WM-CLIK are three separate SKUs with different sensing behaviour, not trim levels of one product. Check the variant selector, not the title.
It reacts. It never forecasts
A hygroscopic-disk sensor triggers after enough rain has landed on the disks to swell them, and needs roughly 19 hours to dry out and release the controller again. It cannot skip the 5 a.m. cycle the morning before a forecast storm — that is a weather-based controller's job. Buy a rain sensor to stop watering during rain, not to plan around it.
