Pressure Sensors Forum Discussions
Hi,
I used sp49 Sensor for my TPMS Application. Instead of RF we are using BLE for Communication. But my sensor power consumption is 0.9mA. Is it possible to reduce the power. How can i reduce the power Consumption
Show LessCan the KP229E3518 sensor be used in a pure hydrogen atmosphere?
Also, what if the sensor is exposed to a pressure above the rated range? At what point is it irreversibly damaged?
Show LessDear,
i have couple of question on pressure sensor KP264 and usage of Diag1\Diag2 .
1- The Diag1 and Diag2 test shall be triggered at start-up or after start-up by means of Diag SPI commands ?
2- The use case UC2 in the safety manual mention a tsafety= 1ms. Does it means that the pressure measurement is available 1ms after the Acquire pressure SPI command? (So opposite to the UC1 where the system shall wait 5 ms before reading the response of a Pressure SPI command).
Show LessHi, I have a KP466 sensor on our boards. It is a shared SPI bus with one CS going to the KP466 and another CS going to a CAN controller. The CAN controller works fine. I have the Vprog line tied to ground as I'm leaving it with the default settings.
Code to read 10-bit pressure:
GPIO_PinOutClear(PRESS_CS_PORT, PRESS_CS_PIN);
vTaskDelay(10);
SPIDRV_MTransferB(sl_spidrv_usart_SPI_handle, tx_val, rx_val, 2);
GPIO_PinOutSet(PRESS_CS_PORT, PRESS_CS_PIN);
vTaskDelay(1000);
GPIO_PinOutClear(PRESS_CS_PORT, PRESS_CS_PIN);
vTaskDelay(10);
SPIDRV_MTransferB(sl_spidrv_usart_SPI_handle, tx_val, rx_val, 2);
GPIO_PinOutSet(PRESS_CS_PORT, PRESS_CS_PIN);
vTaskDelay(10);
uint8_t err = rx_val[0];
err >>= 3;
uint16_t press_raw = rx_val[0] << 8;
press_raw |= rx_val[1];
press_raw &= 0x07FF;
press_raw >>= 1;
There 5-bit error code is not matching documentation, it's consistently 0b10101. The raw 16-bit value returned is 0xa97a.
Furthermore, if I try to read a 10-bit temperature with 0x4000 I always get 0x8000 back. Any help would be much appreciated!
We bought SP4X_DEV_KIT. I am trying to communicate with SP400-15-11 sensor and CC1101 SubGHz transceiver. I can see it's broadcasting on 433MHz. But i can't see the data packets the SP40 is sending.
There is very little information about SP40.
I use CC-Debugger with CC1101 and SmartRF Studio 7.0 from TI. I am sharing my SmartRF Studio 7.0 setting parameters in the attachment.
Which parameters is wrong? How can I build communication CC1101 with SP40?
Show LessHello,
I'm currently using your S2GOPRESSUREDPS368TOBO1 module integrating the DPS368 pressure sensor. Today I received the order for 5 modules, and I noticed something strange on the DPS368 sensor: the metal part on top is detached. .... Is this sensor fragile, or does this problem stem from the delivery conditions? Because in my application there are vibrations, and if your sensor is fragile, this will cause a problem.
Please find attached 2 photos showing the problem encountered.
