Analogue Input Board for the Pressure Sensor (Espiresso)

Analogue Input Board for the Pressure Sensor (Espiresso)

Product description

Having added a pressure sensor to my Espiresso Machine, I needed an analogue input to be able to read the output voltage from the sensor. Unfortunately, the Raspberry Pi doesn’t have analogue inputs, so an external ADC is required. I settled on the Adafruit ADS1015 which has 4 inputs, 12-bit resolution, includes a programmable gain amplifier, and also uses an I2C interface:

There’s some useful information on how to set up I2C on the Pi on the Adafruit site. Having done that, there is sample code available to read the sensor from Python or C. With this, it was pretty easy to get readings from the sensor, and it seems to perform well.

The pressure sensor uses a 5V supply, and has a ratiometric output which ranges from 0.5V to 4.5V, proportional to input pressure. It has a 0-300 psi range (20.68 bar). The absolute maximum analogue input for the ADS1015 is VDD+0.3V. If we are running the ADS1015 from 3.3V for compatibility with the Pi I2C voltage levels, this limits the analogue input voltage 3.6V maximum.

Theoretically, the Ulka EP5 pump can develop up to 15 bar pressure, although this is limited by the OPV in the machine to 9~10 bar. If we assume the maximum pressure is 10 bar, and the response is linear, this would result in a maximum output voltage of:

4V x (10/20.68) + 0.5V = 2.4V

So it seems that for normal use, the output voltage should be below the maximum analogue input voltage limit of 3.6V. Even if we assume peak pressure of 15 bar is possible, that would be a maximum output voltage of:

4V x (15/20.68) + 0.5V = 3.4V

Based on these calculations the current plan is to interface the pressure sensor directly to the ADS1015.

The next step was to interface the board to the Pi in the Espiresso. Unfortunately, the SCL and SDA pins on my Pi are already used as inputs to read the two front panel buttons on the machine (using one GPIO per button). Also, almost all the other GPIOs are in use, so there was no free GPIO available to relocate the buttons.

To make the SCL and SDA lines available for the ADC, I decided to use a resistor ladder to read the buttons. This will make it possible to use a single analogue input to read all the buttons.

I’m also planning to use an opto-coupler to signal the Pi when the brew (pump) switch is switched on. Since that has an open collector NPN output, I plan to connect that to the resistor ladder also, so that it can be treated as another button input.

The pressure sensor and button input will only use 2 of the 4 analogue inputs, so there will be some inputs spare for future use.

HC-12 Wireless Transceiver Module

HC-12 Wireless Transceiver Module

The HC-12 is a half-duplex 20 dBm (100 mW) transmitter paired with a receiver that has -117 dBm (2×10-15 W) sensitivity at 5000 bps. Paired with an external antenna, these transceivers are capable of communicating up to and possibly slightly beyond 1 km in the open and are more than adequate for providing coverage throughout a typical house.

The Si4463 Transceiver The Si4463 provides the wireless communication in this circuit. It has a maximum transmit power of 20 dBm (100 mW) and receive sensitivity of -129 dBm. Two 64-byte Rx and Tx FIFO memories are built into the chip along with a great many advanced features that are not implemented in the HC-12 design. See the datasheet for more information on multiband operation, frequency hopping, etc. The STM8S003FS Microcontroller This is an 8-bit microcontroller with 8 kB of flash memory, 128 bytes of EEPROM, and a 10-bit ADC. It supports UART, SPI, and I²C and has multiple I/O pins. It offers many of the same capabilities as its ATMega and XMC counterparts. It is programmed to control the Si4463 as well as handle the UART communication between the HC-12 and whatever it is connected to on the other end. The HC-12 Transceiver Module Combined with other components, the Si4463 and STM8S003 create the HC-12 transceiver, which provides a 4-pin TTL-level UART interface (Vcc, Gnd, Tx, Rx), with a 5th pin that is used to enter "command" mode for changing the module's configuration. The HC-12 has 100 supported channels spaced 400 kHz apart, eight transmit levels, eight supported baud rates, and three different working modes. The 5th pin on the HC-12 is labeled "Set" and, when driven to logic low, allows various settings to be selected on the HC-12 using AT commands sent to the "RXD" pin. The default configuration of the HC-12 is FU3—on Channel 1, FU3 is a fully automatic and transparent (to other devices) setting that adapts to the transmission rate of the connected device (although 9600 baud is still required to program it in Command mode). Note that as the transmission rate increases, the sensitivity of the receiver decreases. You can return to the default state by sending AT+DEFAULT once in command mode.

ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier

ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier

DESCRIPTION

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 the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 16 bit converter.

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C bus for 16 single ended inputs.

To get you started, we have example code for both the Raspberry Pi (in our Adafruit Pi Python library) and Arduino (in our ADS1X15 Arduino library repository) Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.

EMG SENSOR MUSCLE SENSOR

EMG SENSOR MUSCLE SENSOR

DESCRIPTION:

Granted, using our muscles to control things is the way that most of us are accustomed to doing it. We push buttons, pull levers, move joysticks… but what if we could take the buttons, levers and joysticks out of the equation? That’s right, take the electrical signal straight from the muscle and put it into your device. Thanks to shrinking amplifier technology, we can now do exactly that!

Measuring muscle activity by detecting its electric potential, referred to as electromyography (EMG), has traditionally been used for medical research. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into all kinds of control systems.

This sensor will measure the filtered and rectified electrical activity of a muscle; outputting 0-Vs Volts depending the amount of activity in the selected muscle, where Vs signifies the voltage of the power source. It’s that easy: stick on a few electrodes, read the voltage out and flex some muscles!

This kit comes with everything you need to start sensing muscle activity with your Arduino or controller of choice.
