STEVAL-IDI009V1

STEVAL-IDI009V1 Evaluation board for passive infrared sensor signal conditioning based on TSU102 Description The STEVAL-IDI009V1 evaluation board conditions the signal generated by a passive infrared (PIR) sensor, for common applications like human detection. A person in range of the sensor triggers a detection event, which can in turn be used to trip an alarm or command room lighting to be turned on, for example. The board embeds the TSU102 operational amplifier which consumes only 1 µA. It is highly suitable for battery powered applications such as LED lighting with embedded motion detection to enhance daily comfort. The global application consumes only 24 µA when there is no detection. Features          Allows motion detection with PIR sensor Suitable for home automation applications Based on TSU102 operational amplifier Band pass filter bandwidth from 0.7 Hz to 5 Hz Only 24 µA current consumption Detection area can be widened with Fresnel lens(not included) Compatible with NUCLEO boards Compatible with Arduino UNO R3 RoHS compliant May 2017 DocID030027 Rev 2 For further information contact your local STMicroelectronics sales office 1/4 www.st.com DocID030027 Rev 2 PI R G S D GND VC C GND G S D SB 6 TP1 C2 220µ F 56k GND R1 R2 1.3k 3.3nF C1 3 VC C C8 10nF C7 1µF 1 TSU1 02A 47nF V+ V- 8 2 4 GND C3 R3 680k GND C4 TP2 VC C 22µF C10 10µF GND 10nF C6 470k R7 R4 13k 470k GND R6 5 6 47nF TSU1 02B C5 R5 100k 7 1 TP3 3 R8 100 1M P1 2 1N4 148W -7-F GND C9 10µF SB 5 SB 3 SB 1 GND GND R10 100k R9 10 0 k VC C SB 4 SB 2 SB 0 VC C SB 7 9 10 11 12 13 14 1 2 3 4 5 6 7 8 A0 A1 A2 A3 A4 A5 I OR ef Reset 3.3V 5V GND GND Vin 7 ~6 ~5 4 ~3 2 TX 1 RX 0 Ar ef GND 13 12 ~11 ~10 ~9 8 Arduino UNO PO W ER 2/4 A N A L OG I N 25 26 27 28 29 30 31 32 15 16 17 18 19 20 21 22 23 24 GND 1 D IG IT A L (PW M ~) D1 Schematic diagram STEVAL-IDI009V1 Schematic diagram Figure 1: STEVAL-IDI009V1 circuit schematic GSPG10 11161150SG STEVAL-IDI009V1 2 Revision history Revision history Table 1: Document revision history Date Version Changes 15-Nov-2016 1 Initial release. 10-May-2017 2 Updated Section "Features".
