Multi-Interval Wireless Rain Gauge

This wireless weather station integrates a high-capacity rain gauge and dual-zone temperature monitoring into one compact display unit. The outdoor sensor transmits data up to 100 meters away using 433 MHz radio frequency. Rainfall is reported across five user-selectable periods: 1 hour, 24 hours, week, month, and total since reset — with metric (mm) or imperial (inch) units. Indoor and outdoor temperatures appear simultaneously, with manual date input, calendar display, and switchable 12/24-hour format. The receiver supports zone configuration and alarm alerts, and stands freely on any flat surface. Technical specs include a rain measurement range of 0–19,999 mm, outdoor temp range of -40°C to +65°C, indoor range of -9.9°C to +60°C, and ±1.0°C temperature accuracy. Power is provided by 2 x AA batteries (receiver) and 2 x AAA batteries (sensor), neither included. Housing is made from durable plastic suitable for UK outdoor conditions.
