Burst Sampling with the ADS1115 in Continuous Mode ...

2020-05-21· The 16-bit ADS1115 has a programmable amplifier at the front end, with the highest gain setting providing a range of +/- v and a resolution of about 8 micro volts. But readers of this blog know you can already approach 14-16 bit sensitivity levels with Arduino’s ADC by oversampling with lower Arefs & scaled ranges.

How to use the I2C interfaces of the ESP32 • Wolles ...

2021-05-29· ADS1115_WE adc_1 = ADS1115_WE(&I2C_1, ADS1115_I2C_ADDRESS); ADS1115_WE adc_2 = ADS1115_WE(&I2C_2, ADS1115_I2C_ADDRESS); A TwoWire object has a significant size. Therefore, to save memory space, most libraries do not work with local copies of the objects, but with the objects themselves. For this purpose, the TwoWire object is passed as a pointer, the receiving …

ADS1115 - A/D converter with amplifier • Wolles ...

2021-01-06· With ADS1115_WINDOW, you define a window with maximum and minimum. If values outside the limits are detected, the alert pin asserts. If the ADS1115 then determines values within the limit, the alert pin assertion is cleared – unless latch is active. With ADS1115_MAX_LIMIT, the alert pin only asserts if the maximum is exceeded. The minimum is ...

4-Channel 16-bit ADS1115 Analog to Digital Converter ...

For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to ...

MH-Z19 not working · Issue #446 · kizniche/Mycodo · GitHub

2018-04-10· The MH-Z16 and the MH-Z19 are somewhat different in design and interfacing. I haven’t looked at combining the code modules, mostly since Winsen doesn’t really document reading module type, if I recall. My MH-Z19 sensor had stopped working at some point and I didn’t debug the reason. I assumed a problem on my side and didn’t suspect a code regression. tl,dr: the fix is only the one line ...

ADS1115 4-Channel 16-Bit ADC Module - ProtoSupplies

2021-07-31· The ADS1115 is a 16-bit device, but in single-ended mode the output is a signed integer and one of the bits is used for the sign so in practice it is providing 15-bits of resolution which means there are 32,767 steps of resolution. The maximum voltage that can be measured and thus the size of the steps of resolution is controlled by the Programmable Gain Amplifier (PGA). The PGA has 6 full ...

ADS1115: Current limit is only +- 2V. "Dangerous" and ...

2017-12-01· In the function Ads1115StartComparator there is a default used for the voltage range that can be most devices run with or even 5V the current default: ADS1115_REG_CONFIG_PGA_2_048V = +-2V is not a good idea. The used default in the i2cdev library is ADS1115_REG_CONFIG_PGA_6_ would suggest using this also in the xns_12_ …
