Don’t edit by hand — edit the data. Comparison Part Role Interface Verdict Price Split-core CT clamp (x2) Current sensing on both 120 V legs of the panel Analog into ADS1115 A2/A3 conditional — JANSANE SCT-013-000 100 A split-core CT clamp. Works, but a split core that is not fully closed reads low silently. Calibration constant is empirically fitted. ADS1115 16-bit I2C ADC breakout Reads the two CT clamps (channels A2/A3) for whole-house current I2C, single-ended A2/A3 conditional — HiLetgo ADS1115 16-bit 4-channel I2C ADC.https://sensorrig.com/rig/guides/ds18b20-troubleshooting-guide/Fri, 14 Aug 2026 00:00:00 +0000https://sensorrig.com/rig/guides/ds18b20-troubleshooting-guide/This guide is generated from data/guides.json and data/parts.json.

Comparison Part Role Interface Verdict Price DS18B20 (x8) 1-Wire temp probes (house) Pi 4 w1-gpio bus, mixed 9/12-bit yes — Waterproof DS18B20 probe with stainless steel sleeve, includes 4.7kΩ resistor. Buy the 2-pack. 3M 3811/10 flat ribbon DQ / power wiring to probes 2-3 m runs, ~45 pF/m — — Jacket print to confirm AWG (listed 26 by distributors, searay noted 28).https://sensorrig.com/rig/guides/energy-monitoring-raspberry-pi/Fri, 14 Aug 2026 00:00:00 +0000https://sensorrig.com/rig/guides/energy-monitoring-raspberry-pi/This guide is generated from data/guides.json and data/parts.json.

Comparison Part Role Interface Verdict Price HC-12 433 MHz wireless module Radio link shed <-> Pi 4 Serial1, 9600 baud, RX20/TX21 yes — HiLetgo HC-12 433 MHz SI4438 module with antenna. Reliable for 100–1 000 m links. ESP32-C3 dev board Shed node MCU GPIO; Serial1 HC-12 (RX20/TX21); I2C SDA8/SCL9 yes ~$10.99 The shed node MCU.https://sensorrig.com/rig/guides/temperature-sensors-raspberry-pi-2026/Fri, 14 Aug 2026 00:00:00 +0000https://sensorrig.com/rig/guides/temperature-sensors-raspberry-pi-2026/This guide is generated from data/guides.json and data/parts.json.

Buy the 2-pack. DHT22 Outside air temp + humidity GPIO 0 yes — Used in the running shed build; works reliably. BMP180 Pressure + internal temp I2C 0x77 yes (use BME280 instead) — BMP180 is what’s in the shed node (had it lying around); BME280 is the current part, adds humidity, and is what I’d buy today.
