3.3 V-powered pH and ORP probe interface using an ADS1115 module, MCP6002 through-hole buffers, and DS18B20 temperature sensing. External ESP32 connection is through one 5-pin header carrying 3V3, GND, SDA, SCL, and DQ; ADS1115 ADDR is fixed locally and ALERT is unused.

SOT-23-5 is a small 5-pin Surface Mount Device (SMD) package with a body size of 3mm x 1.4mm and a lead pitch of 0.95mm. The package has a low profile and is commonly used for small signal transistors and diodes. #part #template
