Special caution should be taken when operating at greater than ±20 volts in a situation where significant current can be supplied. Many solar panel projects require measurement of more than 0.6 amperes of current so these concepts is often useful...

If the reading of a Stainless Steel Temperature Probe (TMP-BTA) or Surface Temperature Sensor (STS-BTA) never changes or gives erroneous readings, it is probably damaged and can not be repaired. Often a damaged sensor reads -273 degrees C or a value ...

The Vernier Breadboard Cables (Breadboard Cable (Analog) (BB-BTA) and Breadboard Cable (Digital) (BB-BTD)) provide an easy way to connect your sensor to a Vernier interface. Once your sensor is connected to an interface, you can use Logger Pro to c...

Sound level apps for both iOS and Android abound, turning any smartphone into a sound level meter. Given the low cost of these apps, why would you purchase a commercial sound level meter like the Go Direct® Sound Sensor (GDX-SND), Sound Level Met...

The Microphone (MCA-BTA) output signal is sent to the interface on two different lines: 1) A signal centered at 2.5 volts is on the standard 0-5V output line. 2) A signal centered at 0 volts is on the alternate +/-10V output line. Here is a pi...

Ethyl acetate and some of the other solvents used in Experiment 29, "The Base Hydrolysis of Ethyl Acetate," in Advanced Chemistry with Vernier can quickly degrade the ABS plastic bodies of our standard Conductivity Probe (order code: CON-BTA) and our...

There are several styles of Vernier Dissolved Oxygen probes, and each probe is compatible with different software. See the table below for which probes are compatible with which software. ProductCompatible SoftwareInterface Required?Dissolved Oxy...

In October/November of 2018 we shipped some UVB Sensor (UVB-BTA) that were assembled with the label on the tube that says Relative Humidity Sensor (RH-BTA). They were sold as UVB sensors and came in bags labeling them as UVB sensors and they do work...

Use the picture below to determine which Apogee sensor your PAR Sensor (PAR-BTA) has. Starting in May 2023, all Vernier PAR sensors, including Go Direct® PAR (Photosynthetically Active Radiation) (GDX-PAR), use the Apogee SQ-100x sensor head...
