HALO2 GroLine Wireless pH Tester
The HALO2 GroLine Wireless pH Tester is designed to bring simplicity to pH testing of soil for environmental and agricultural purposes.
- Open-source Bluetooth allows easy integration into current data logging systems
- IP65 water resistant protection
- Specialized electrode for spot checking the pH of soil and soil slurries
This meter comes with the highly accurate VH400 soil moisture sensors with a 1.2 meter (4 ft) cable. The VH400 probe is slender so it will not disrupt the root system of your plants. It's also rugged, waterproof and will never corrode. Because it uses transmission line techniques to measure moisture, the VH400 probe is insensitive to soil salinity. Soil moisture results are displayed as a simple percentage (VWC) and ranges from 0 to 100%.
The meter can display ambient temperature either in Celsius or Fahrenheit. The temperature is measured at the hand held unit. The VG-METER-200 displays light levels in Lux.
Munsell Soil Color Book
Included are a 10Y and 5GY soil chart for glauconite soils, a 5R soil chart for Australia and Southeast Asia, and a 7.5R soil chart for tropical and semi-tropical soils.

Use this page to describe carbonate, silica, gypsum, and soluble salt precipitates and evaporites common to arid and semi-arid environments as well as very light-colored parent materials such as diatomaceous earth and volcanic ash.

Surveying Instruments (High Accuracy)
4.5 inch Transit, David White
For the mechanically-minded, non-powered types: not electronic -- no batteries -- completely opto-mechanical. Takes patience and practice, but you can get accuracy to minutes of horizontal and vertical angle.
Telescopic (optical) level. Use tape or stadia readings for distance.
Used with stadia rod in meters or feet.
Laser level. Used with laser sensor (in laser level box) mounted on suitable rod, such as the Direct Reading Laser Leveling Rod.
Leica Total Station (Builder 503)
The Leica Builder 503 Total Station is a relatively easy-to-use instrument, but has exceptional accuracy: 3 seconds of angle horizontally and vertically. See the SFSU Guide for a shortened version of the manual focused on our uses, which are going to be for capture of survey points, referred to as an "As-Built" survey (the instrument also does "Layout" for construction.)
Uncrewed Aircraft Systems (UAS)
The 300-g DJI Spark can't be programmed to fly autonomously, but it has a decent camera that can be used to map using GCPs and manual flying even with no GPS. The procedure uses Free-Flight mode in Pix4Dcapture, which triggers the camera at specified spacing.
DJI Phantom 4 Advanced
The DJI Phantom 4 is a popular, easy-to-fly UAS that integrates a decent camera (1" CMOS 20 Mpixel 100-12800 ISO, FOV 84° 8.8 mm (24 equiv) f/2.8-f/11, autofocus) on a gimbal. One advantage over the Phantom 3 is locking propellers.

Cameras & Sensors and Vehicles
The Canon S95 is a versatile but inexpensive camera with a global shutter, so it works well with on a UAV platform. Run the CHDK intervalometer to take pictures at regular intervals. We have three of these, one unaltered, the other two with the IR blocking filter removed, one with a filter mount, the other with an NGB filter installed internally.
GoPro Hero 3+ Silver Edition.
MicaSense RedEdge Multispectral Camera
The MicaSense RedEdge 5-band sensor was designed primarily for precision agriculture applications, where farmers can look for moisture and other stress on their fields, but also works well for vegetation mapping. It captures narrow bands of blue (centered on 475 nm), green (560 nm), red (668 nm), near infrared (NIR, 840 nm), and red edge (717 nm), allowing for accurate detection of vegetation health and discernment of species based on their spectral signatures.
