About this app
Soil Testing is a professional field tool for reading compatible soil sensors through an Android USB Host serial connection.
Connect a supported USB-to-serial adapter using USB OTG, then read eight soil parameters at 1 Hz:
• Moisture
• Temperature
• Electrical conductivity (EC)
• pH
• Nitrogen
• Phosphorus
• Potassium
• Fertility
Key features:
• USB serial communication at 9600 baud, 8N1
• Support for common CH340, CP210x, FTDI and CDC ACM adapters
• Modbus RTU CRC validation and reliable frame handling
• Continuous one-touch sensor measurement
• Local history stored on your device
• CSV export compatible with Excel
• Save files or share them using Android system tools
• English and Chinese interface
The app does not require an account, does not display ads, and does not upload sensor readings. Measurement records remain on your device unless you choose to export or share them.
A compatible USB soil sensor and USB OTG connection are required.
