STEVAL-IDI009V1 STMicroelectronics

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 A. 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 A 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 A 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 1/4 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram STEVAL-IDI009V1 1 Schematic diagram Figure 1: STEVAL-IDI009V1 circuit schematic GSPG10 11161150SG 2/4 DocID030027 Rev 2 15 Arduino UNO D1 1N4 148W -7-F 16 17 Ar ef 18 GND 1 19 R3 13 2 20 680k IOR ef 12 VC C 3 21 GND ~11 Reset R5 P1 1 3 4 22 ~10 100k 3.3V C3 47nF 5 23 5V ~9 1M 6 24 8 GND 7 GND C5 47nF 8 25 7 Vin GND GND 26 ~6 TP2 TP3 SB 0 9 27 A0 ~5 SB 1 10 28 A1 4 TSU1 02A SB2 11 29 R2 A2 ~3 C2 220F TSU1 02B 2 SB 3 12 30 GND A3 1.3k R4 2 V- 1 C4 22F 6 SB 4 13 31 A4 13k R8 TX 1 V+ 3 7 SB 5 14 32 C10 A5 100 RX 0 VC C 5 10F C9 TP1 SB 7 10F C7 1F D VC C D GND SB6 GND S C1 S R1 VC C GND R9 G VC C 470k G 3.3nF C8 10nF 100k R7 PIR C6 R10 R6 GND 10nF 100k GND GND GND 56k 8 4 470k 2 A NA L OG IN POW ER D IGITA L (PW M ~)
